PREDICT Subcommand (SURVREG RECURRENT command)
PREDICT is an optional subcommand to score and save the predicted statistics to
the active data set. If specified, one of SURVIVAL, HAZARD, CUMHAZARD, UNCONDSURVIVAL, UNCONDHAZARD,
and UNCONDCUMHAZARD must be specified or both PASTIME and CONDITIONALSURVIVAL must be specified.
- FUTUREDURATION
- An optional keyword to specify the time duration to define the future time values for scoring. If specified, it must be followed by a single numeric variable that is specified within parentheses.
- FUTUREINTERVALS
- A keyword to alternatively define the future time values. If specified, it must be followed by
two additional parameters BETWEEN and PERIODS specified within parentheses. BETWEEN controls the
time interval. It must be a single numeric value greater than 0. PERIODS controls the number of the
time periods. It must be a single numeric integer that belongs to [2, 100]. Additional restrictions
are placed on FUTUREDURATION and FUTUREINTERVALS as follows:
- If either FUTUREDURATION or FUTUREINTERVALS is specified, the scoring of SURVIVAL, HAZARD, and CUMHAZARD is then based on the time values defined by either of them. Otherwise, the scoring is based on the time variable that is specified for the parametric survival model.
- If both FUTUREDURATION and FUTUREINTERVALS are specified, the process checks whether the variable that is specified for FUTUREDURATION is valid. If it is a valid setting, FUTUREINTERVALS are ignored, and the scoring is based on the time values that are defined by FUTUREDURATION. Otherwise, the scoring is based on FUTUREINTERVALS, and FUTUREDURATION is then ignored.
- SURVIVAL
- An optional keyword to score and save the predicted survival statistics to the active dataset. The keyword is suppressed by default. If specified, it could be followed by an optional user-supplied variable name (or root name) specified within parentheses. The default name is "PredSurvival."
- HAZARD
- An optional keyword to score and save the predicted hazards to the active data set. The keyword is suppressed by default. If specified, it can be followed by an optional user-supplied variable name (or root name) specified within parentheses. The default name is "PredHazard."
- CUMHAZARD
- An optional keyword to score and save the predicted cumulative hazards to the active dataset. The keyword is suppressed by default. If specified, it might be followed by an optional user-supplied variable name (or root name) specified within parentheses. The default name is "PredCumHazard."
- PASTTIME
- An optional parameter to specify the past time values for scoring. If specified, it must be followed by a single numeric variable that is specified within parentheses. If CONDITIONALSURVIVAL is not specified, the process is ignored
- CONDITIONALSURVIVAL
- An optional keyword to score and save the predicted conditional survival statistics to the active data set. The keyword is suppressed by default. If specified, it might be followed by an optional user-supplied variable name that is specified within parentheses. The default name is “PredConditionalSurvival”. The process is ignored if PASTTIME is not specified.
- UNCONDITIONALSURVIVAL
- An optional keyword to score and save the predicted unconditional survival statistics to the active data set. The keyword is suppressed by default. If specified, it might be followed by an optional user-supplied variable name (or root name) specified within parentheses. The default name is "PredUncondSurvival".
- UNCONDHAZARD
- An optional keyword to score and save the predicted unconditional hazard statistics to the active data set. The keyword is suppressed by default. If specified, it might be followed by an optional user-supplied variable name (or root name) specified within parentheses. The default name is "PredUncondHazard".
- UNCONDCUMHAZARD
- An optional keyword to score and save the predicted unconditional cumulative hazard statistics to the active data set. The keyword is suppressed by default. If specified, it might be followed by an optional user-supplied variable name (or root name) specified within parentheses. The default name is "PredUncondCumHazard".
