PATTERN Subcommand (COXREG command)

PATTERN specifies the pattern of covariate values to be used for the requested plots and coefficient tables.

• A value must be specified for each variable specified on PATTERN.
• Continuous variables that are included in the model but not named on PATTERN are evaluated at their means.
• Categorical variables that are included in the model but not named on PATTERN are evaluated at the means of the set of contrasts generated to replace them.
• You can request separate lines for each category of a variable that is in the model. Specify the name of the categorical variable after the keyword BY. The BY variable must be a categorical covariate. You cannot specify a value for the BY covariate.
• Multiple PATTERN subcommands can be specified. COXREG produces a set of requested plots for each specified pattern.
• PATTERN cannot be used when time-dependent covariates are included in the model.
