BASELINE Statement

BASELINE <OUT=SAS-data-set> <COVARIATES=SAS-data-set> < keyword=name …keyword=name> ;

The BASELINE statement creates an output data set to contain the survival function estimates or the conditional quantile function estimates for every set of covariates ( $\mb {x}$ ) in the COVARIATES= data set. If the COVARIATES= data set is not specified, PROC QUANTLIFE uses a reference set of covariates that consists of the reference levels for the CLASS variables and the average values for the continuous variables.

The following options are available in the BASELINE statement.

OUT=SAS-data-set

names the output data set. If you omit the OUT= option, the data set is created and given a default name by using the DATAn convention. See the section OUT= Output Data Set in the BASELINE Statement for more information.

COVARIATES=SAS-data-set

names the SAS data set that contains the sets of explanatory variable values for which the quantities of interest are estimated. All variables in the COVARIATES= data set are copied to the OUT= data set. Thus, the variables in the COVARIATES= data set can be used to identify the covariate sets in the OUT= data set.

keyword =name

specifies the statistics to be included in the OUT= data set and assigns names to the variables that contain these statistics. Specify a keyword for each desired statistic, an equal sign, and the name of the variable for the statistic.

You can specify the following keywords:

SURVIVAL: specifies the estimated survival function.
QUANTILE: specifies the estimated quantile function.
TAU: specifies the quantile level, which is the complement of the survival function.
