CRITERIA Subcommand (SURVREG AFT command)

CRITERIA is an optional subcommand that specifies the general criteria.

CLASSMISSING

An optional parameter to control how the user-missing values are treated. EXCLUDE is the setting by default, which treats the user-missing values as valid values. INCLUDE ignores the user-missing value designations and treats them as valid values.

CILEVEL

An optional parameter to specify the level for the confidence intervals of regression parameters. It must be a single numeric value belonging to (0, 100). The default setting is 95.

TREATMENT

An optional parameter to control how to deal with those records whose status field is not correct. DISCARD is the setting by default, which will drop the conflicted records. CONFORM will get the time information according to the status. DERIVE will change the status according to the time information. The process will be ignored if a single dependent variable is specified after SURVREG AFT.
