The default value equals the maximum event time. a pivot for sweeping a covariance matrix be at least this number times a norm of the matrix. The PROC LIFETEST statement invokes the procedure. specifies how to display the survival/failure curves for multiple strata. Each interval contains its lower endpoint estimates, unless you use the FAILCODE option in the TIME statement to stipulate a competing-risks analysis. LOGSURV LOGLOGS DENSITY HAZARD). option. option is specified. 72–76). If you specify the LINEPRINTER option, you get line printer plots; otherwise you get the traditional graphics if ODS Graphics is not enabled, and you get the ODS Graphics plots if the ods graphics on statement is specified. You can specify one selects the bandwidth from the interval (lower, upper) that minimizes the mean integrated squared error. These endpoints must all be nonnegative numbers. suppresses the display of survival function estimates. creates an output SAS data set to contain the estimates of the survival function and corresponding confidence limits for all strata. For the equal-precision band, if the BANDMIN= value is less than the smallest observed event time, it is defaulted to the smallest observed event time. data set contain only those observations that are included in the INTERVALS= You can specify covariates in the TEST statement. estimate. The Breslow estimator is the exponentiation of the negative Nelson-Aalen These options are described in alphabetic order. option nor the TIMELIST= The options listed in Table 49.1 are available in the PROC LIFETEST statement and are described in alphabetic order. The TIME statement specifies the variables … Table 70.1: Options Available in the PROC LIFETEST Statement, Names an output data set to contain cumulative incidence function (CIF) estimates, Names an output data set to contain survivor function estimates, Names an output data set to contain rank test statistics for association of survival time with covariates, Specifies the variance method of the CIF estimator, Specifies interval endpoints for life-table estimates, Specifies the method to compute survivor function, Specifies the number of intervals for life-table estimates, Specifies the width of intervals for life-table estimates, Sets the confidence level for interval estimation estimates, Specifies the maximum time for confidence band, Specifies the minimum time for confidence band, Specifies the type of confidence band in the OUTSURV= data set, Specifies the transformation applied to the survivor function to obtain confidence limits, Specifies the maximum time value for plotting, Adds the number of subjects at risk to the survival estimate table, Suppresses the display of survival function estimates, Displays only the estimate for the smallest time in each interval, Suppresses the Number Left column in the survival estimate table, Specifies a list of time points to display the survival estimate, Specifies that only INTERVAL= or TIMELIST= observations be listed in the OUTSURV= data set, Sets the confidence level for survival time quartiles, Displays the variance of the CIF estimator, Allows missing values to be a stratum level, Sets the tolerance for testing singularity of covariance matrix of rank statistics, Outputs the standard error for the survival estimators to the OUTSURV= data set, Specifies the time limit used to estimate the mean survival time and its standard error. specifies the time limit used in the estimation of the mean survival time and its standard error. Note that this option temporarily disables the Output Delivery System (ODS); see outputs the equal-precision confidence bands. In such a situation, you can choose a time limit L and estimate the mean survival curve limited to a time L (Lee 1992, pp. SAS, PROC LIFETEST, PROC PHREG, DURATION, SURVIVAL, HAZARD RATIOS, DISEASE PROGRESSION, TREATMENT FAILURE, PROGRESSION FREE SURVIVAL, RESPONSE INTRODUCTION To create these Oncologic Efficacy Summary Tables use the SAS procedures PROC LIFETEST and PROC PHREG. controls the plots produced using ODS Graphics. The mean survival time can Here are some examples: You must enable ODS Graphics before requesting plots—for example, like this: specifies that only the specified plots in the list be produced; otherwise, the default survivor function plot is also displayed. specifies the upper grid limit for the kernel-smoothed estimate. This option has no effect if you use the FAILCODE option in the TIME statement to stipulate a competing-risks analysis. Optionally, this statement identifies an input and an OUTSURV= data set, and specifies the computation details of the survivor function estimation. but does not contain its upper endpoint. The default value equals the maximum event time. option. Here are some examples: The latter requests a plot of the estimated survivor function versus time and a plot of the estimated hazard function versus time, with Surv2 and Haz2 as their names in the GOUT= catalog, respectively. If there is no BY-group processing, the ANNOTATE= and LANNOTATE= options have the same effects. names the SAS data set used by PROC LIFETEST. See the section Missing Values for details. specifies the kernel used. ; The PROC LIFETEST statement invokes the LIFETEST procedure. For This option affects only the displayed plots and has no effect on any calculations. If there is more than one local minimum in the interval, there is no guarantee that the local minimum found is also the global SAS Proc Lifetest. If the specified BANDMAX= time By default, the most recently created SAS data set is used. Some commonly created efficacy outputs used for these analyses … The default is NINTERVAL=10. The corresponding tests are known as the log-rank test and the Wilcoxon test, respectively. You can specify the following hazard-options, but only the CL option can be used for the life-table method: specifies what bandwidth is chosen for the kernel-smoothing and how it is chosen. Copyright specifies that the at-risk table be drawn outside the plot area. specifies a list of interval endpoints for the life-table method. treats missing values as valid values for the stratum variables. This option is ignored OUTTEST= data set, see the section OUTTEST= Data Set. creates an output SAS data set to contain the estimates of the survival function and corresponding confidence limits for all specifies the lower grid limit for the kernel-smoothed estimate. For METHOD=KM, METHOD=BRESLOW, or METHOD=FH, specifying PLOTS=ALL is equivalent to specifying This option has no effect if there is only one stratum. If the number-list is not specified, PROC LIFETEST uses the default list , where and are computed by the following algorithm. Table 70.1 summarizes the options available in the PROC LIFETEST statement. outputs the equal-precision confidence bands. the censoring variable as given in … displays both the equal-precision and the Hall-Wellner bands. You can specify an optional PROC LIFETEST uses the golden section search algorithm to find the minimum. suppresses the display of output. variables in the TEST statement, the values of the univariate rank test statistics for each variable in the TEST statement, The test requires that a pivot for sweeping a covariance matrix be at least this number times a norm of the matrix. Any character or hexadecimal string can be used to customize the plot appearance. The ANNOTATE= option cannot be used if the LINEPRINTER option or the ods graphics on statement is specified. This option is not needed when the life-table method is used to compute the survival estimates, since the plot of censored observations is not produced. specifies the number of grid points in determining the mean integrated square error (MISE). When you specify the NINTERVAL= option, PROC LIFETEST tries to find an interval that results in round numbers for the endpoints. This option is ignored unless METHOD=PL. You can specify covariates in the TEST statement. For general information about ODS Graphics, see minimum. (For more information, see the section Modifying the Survival Plots.). The default value is 51. specifies the number of grid points. creates an output SAS data set to contain the overall chi-square test statistic for association with failure time for the variables in the TEST statement, the values of the univariate rank test statistics for each variable in the TEST statement, and the estimated covariance matrix of the univariate rank test statistics. GROUP= option, PROC LIFETEST produces a panel plot, with one cell per stratum, and each cell contains the cumulative incidence The default value is 1E–12. curves for the groups within the given stratum. specifies that the Fleming-Harrington (FH) estimates be computed. Ma proc lifetest me sort un graphique avec deux courbes de couleurs différentes. allows missing values for numeric variables and blank values for character variables as valid stratum levels. outputs the Hall-Wellner confidence bands. For example, the option ALPHA=0.05 requests the 95% confidence limits for the survivor function. The number must be positive and at least as large as the largest event time in the data. The default is CS=CIRCLE. option. The CENSOREDSYMBOL= option cannot be used if the LINEPRINTER option or the ods graphics on statement is specified. is not necessary. The following keywords can be used; the default is CONFTYPE=LOGLOG. When you specify only one plot-request, you can omit the parentheses around the plot-request. Only the number of censored and event times, plots, and test results is displayed. These endpoints must all be nonnegative numbers. PROC LIFETEST computes linear rank statistics to test the effects of these covariates on survival. the area under the survival curve is not a closed area. The FH estimator is a tie-breaking modification of the Breslow The value, name or ’string’, is the symbol value specification allowed in SAS/GRAPH software. example, you can display the number of subjects at risk in a survival plot. The time points are listed in the column the theory of counting process (Aalen 1978). specifies how to display the survival/failure curves for multiple strata. interval is assumed to start at zero whether or not zero is specified in the list. You can customized the display by using the following survival-options. You can specify the OUTCIF= option in the PROC LIFETEST statement to create an output data set that contains the cumulative incidence estimates. Click on “Help” on the toolbox of the program editor. Je n'arrive pas à faire ce que je veux. displays the p-value of a homogeneity test specified in the STRATA statement. changes all the displays for survivor functions to those for the failure functions. If the FORMCHAR option in PROC LIFETEST is not specified, the value supplied, if any, with the system option FORMCHAR= is used. Only the first eight characters are used as the entry name in the GOUT= catalog. It also has no effect if neither the INTERVALS= specifies that life-table (or actuarial) estimates be computed. specifies the symbol value for the censored observations in traditional graphics. specifies that life-table estimates (also known as actuarial estimates) be computed. PROC LIFETEST computes linear rank statistics to test the effects of these covariates on survival. otherwise, the stratum numbers are used. creates an output SAS data set to contain the overall chi-square test statistic for association with failure time for the The PROC LIFETEST statement invokes the procedure. The default value is the time origin. specifies that the survival/failure curves for the strata be overlaid in one plot. LIFETEST PROC can also be used to compute nonparametric estimate of the survivor function by the life table method. The PLOTS= option syntax is documented separately for each type of graphics and is preceded by a heading that indicates the graphics type. The description does not appear in the plots. For more information about the contents of the OUTCIF= data set, see the section OUTCIF= Data Set. In such a case, For more information about the contents of the OUTSURV= data set, see the section OUTSURV= Data Set. plots the cumulative incidence function (CIF) estimates. This can be done using Greenwood's formula. If you specify Optionally, this statement identifies an input data set and an output data set, and specifies the computation details of the survivor function estimation. The data set specified with the ANNOTATE= option in the PROC LIFETEST statement is "global" in the sense that the information in this data set is displayed in every plot produced by a single invocation of PROC LIFETEST. When you specify the NINTERVAL= option, PROC LIFETEST tries to find an interval that results in round numbers for be shown to be the area under the Kaplan-Meier survival curve. The PROC LIFETEST statement invokes the procedure. options are specified, the plot displays the failure curves in addition to the pointwise confidence limits for the failure I want to extract the median ( and mean) survival time from proc lifetest. Also added is a column that represents These tests are computed by pooling over any defined strata, thus adjusting for the stratum variables. The plot-requests and plot-request options include the following. For the product-limit method, specifying PLOTS=ALL is equivalent to specifying PLOTS=(SURVIVAL LOGSURV LOGLOGLS HAZARD); for the life-table method, it is the same as specifying PLOTS=(SURVIVAL LOGSURV LOGLOGS DENSITY HAZARD). For more information, see interval for the quartiles of the survival time. Missing Values; Computational Formulas; Computer Resources; Output Data Sets; Displayed Output ; ODS Table Names; ODS Graphics; Examples: LIFETEST Procedure. See the section Optimal Bandwidth for details about the mean integrated squared error. You can choose one of the following strata options: specifies that a separate plot be displayed for each stratum. specifies that tick values on the time axis be shown only at the times that are given in the ATRISK= list. The ANNOTATE= option enables you to add features (for example, labels explaining extreme observations) to plots produced on graphics devices. the endpoints. The DESCRIPTION= option cannot be used if the LINEPRINTER option or the ods graphics on statement is specified. Use the INTERVALS= the number of events at each observed time. (module SAS/Stat) sans nécessité le module SAS/Graph. the number of survival estimates displayed by showing only the estimates for the smallest time within each specified interval. If the BANDWIDTH= option is not specified, the default is BANDWIDTH= Node 2 of 127.

This option has no effect if the OUTSURV= You can specify one of the following. specifies that Kaplan-Meier estimates (also known as the product-limit estimates) be computed. The choices are as follows: specifies the number of grid points in determining the mean integrated square error (MISE). This is done with the PROC LIFETEST procedure. specifies the maximum time for the confidence bands. For example, the option ALPHA=0.05 requests the 95% displays the p-value of Gray’s test (Gray 1988) for testing the homogeneity of CIFs. Hi folks, Does anyone know whether I can use phreg or lifereg or lifetest to model following survival analysis data structure? changes all the displays for survivor functions to those for the failure functions. The PROC LIFETEST documentation contains a section Computer Resources where memory requirements are presented in detail. displays the confidence bands (that is, simultaneous confidence intervals) for the survivor functions. Is there a way to just get the quartiles table using Proc lifetest. The data set contains the following columns: any specified BY variables. The default is CB=HW. For example, you can display the number of subjects at risk in a survival plot through ODS Graphics, but such a feature is not available in traditional graphics or line printer plots. the section Estimation of the CIF. If you specify a STRATA statement with the by the INTERVALS= I have tried running this proc template and then running my lifetest code but I do not quite understand how to get this template "into" the lifetest procedure. or TIMELIST= By default, PROC LIFETEST assigns a description of the form PLOT OF vname vs hname, where vname and hname are the names of the y variable and the x variable, respectively. For more information, see the section Missing Values. Quant aux sorties SAS à interpréter, rien de vraiment "sorcier" : rien de très spécifique dans l'estimateur de KM puisqu'il s'agit surtout de tracer la courbe du même nom. For example, the option ALPHAQT=0.05 requests a 95% confidence interval for the quartiles of the survival time. are also output. Let be the MAXTIME= value or the largest observed time if the MAXTIME= option is not specified; let , where ceil() is the ceiling function. specifies that the time limit L be the given number. I am using proc lifetest to create survival plots. The ODS TRACE ON statement writes the trace record of ODS output tables. option is not specified. If ODS Graphics is enabled but you do not specify the PLOTS= option, PROC LIFETEST produces a plot of the survivor function You can specify one of the following. controls the plots produced using ODS Graphics. specifies the transformation applied to to obtain the pointwise confidence intervals and the confidence bands for the survivor function in addition to the confidence If these options are not sufficient for your purposes, you can customize the survival plot by modifying its graph template. estimator of the cumulative hazard function. specifies that separate plots for the strata be organized into panels of two or four plots, depending on the number of strata. You can specify the following cif-options: displays pointwise confidence limits for CIF. The PLOTS= option in the PROC LIFETEST statement specifies the plots to display. produces the Nelson-Aalen estimates of the cumulative hazards and the corresponding standard errors. sets the width of the intervals used in the life-table calculation of the survival function. This is also referred to as the log cumulative hazard transformation since it applies the logarithmic function to the cumulative When you specify only one plot-request, you can omit the parentheses around the plot-request. displays the numbers of subjects at risk at the given times. Consequently, the number of intervals can be different from the number requested. specifies a list of time points at which the Kaplan-Meier estimates are displayed. Each interval contains its lower endpoint but does not contain its upper endpoint. output data set, and specifies the computation details of the survivor function estimation. specifies D'autre part je souhaiterais changer le nom de l'axe des ordonnées. By default, ERROR=AALEN. This option is useful when only an output data set is needed. Pointwise confidence limits are displayed optionally When ERROR=AALEN, the variance estimator is based on PLOTS=(SURVIVAL LOGSURV LOGLOGLS HAZARD); for the life-table method, specifying PLOTS=ALL is equivalent to specifying PLOTS=(SURVIVAL I want to change the minimum on the y-axis from 0 to, say, 0.5. Search; PDF; EPUB; Feedback; More. If the ATRISKTICKONLY option is also specified, it takes precedence over the ATRISKTICK option. specifies that separate plots for the strata be organized into panels of two or four plots, depending on the number of strata. The following keywords can be used and the default is CONFTYPE=LOGLOG. PROC LIFETEST Statement; BY Statement; FREQ Statement; ID Statement; STRATA Statement; TEST Statement; TIME Statement; Details: LIFETEST Procedure. PROC LIFETEST uses the golden section search algorithm to find the minimum. the minimum time for the confidence bands. This option is useful when only an output data set is needed. By default, the most recently created SAS data set is used. specifies the graphics catalog for saving traditional graphics output from PROC LIFETEST. displays the variance of the cumulative incidence function (CIF) estimator for competing-risks data.
