proc phreg baseline

specifies the cumulative incidence function estimate for competing-risks data. If the ROWID= option is not specified, the curves produced are identified by the covariate values if there is only a single covariate or by the observation numbers of the COVARIATES= data set if the model has two or more covariates. specifies the significance level of the confidence interval for the survivor function. PROC PHREG is a SAS procedure that implements the Cox model and provides the hazard ratio estimate. If the COVARIATES= data set is not specified, the input data set specified in the The variables Zj are either fixed or time-varying. For simple uses, only the PROC PHREG and MODEL statements are required. This value is used as the default confidence level for limits computed by the BASELINE, BAYES, CONTRAST, HAZARDRATIO, and MODEL statements. specifies the lower pointwise confidence limit for the cumulative hazard function. specifies the log of SURVIVAL names a variable in the COVARIATES= data set for identifying the baseline function curves in the plots. The confidence level is determined by option: If you also specify the DIRADJ data set. You can specify the following options in the PROC PHREG statement. See the section Specifics for Bayesian Analysis for details. For clarity, the COVARIATES=MYELOMA is specified in the BASELINE statement in the preceding PROC PHREG call. option. specifies the lower pointwise confidence limit for the cumulative mean function. ; The BASELINE statement creates a SAS data set (named by the OUT= option) that contains the baseline function estimates at If there are no tied event times, this estimator is the same as the Breslow estimator. the event times of each stratum for every set of covariates in the COVARIATES= data set. Specifies the output data set that contains differences of direct adjusted survival curves, Specifies the SAS data set that contains the explanatory variables. option. The value number must be between 0 and 1; the default value is 0.05, which results in 95% intervals. computes direct adjusted survival curves (Makuch, 1982; Gail and Byar, 1986; Zhang et al., 2007) by averaging the estimated survival curves for the observations in the COVARIATES= data set. specifies how the curves for the various strata and covariate sets are overlaid. The confidence level is determined If the MULTIPASS option is not specified, PROC PHREG computes all risk sets and all the variable values and saves them in a utility file. We frequently use the ods select statement before proc phreg to limit the amount of output produced by SAS. specifies the estimated standard error of the cumulative hazard function estimator. (e.g., the BASELINE statement in PROC PHREG). All You can specify the following methods: specifies that the Breslow (1972) estimator be used to compute the survivor function—that is, that the survivor function be estimated by exponentiating the Copyright For plotting more than one curve, you can use the OVERLAY= option to group the curves in separate plots. For clarity, the COVARIATES=MYELOMA is specified in the BASELINE statement in the preceding PROC PHREG call. See the section OUT= Output Data Set in the BASELINE Statement for more information. specifies the lower pointwise confidence limit for the survivor function.
