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 â¦ 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.
