CSCOXREG

CSCOXREG is available in Sampling and Testing.

For samples drawn by complex sampling methods, CSCOXREG applies Cox proportional hazards regression to analysis of survival times—that is, the length of time before the occurrence of an event.

Note: Square brackets used in the CSCOXREG syntax chart are required parts of the syntax and are not used to indicate optional elements. Equals signs (=) used in the syntax chart are required elements. All subcommands are optional.
