SAVE Subcommand (CSCOXREG command)

The SAVE subcommand writes optional model variables to the working data file.

  • Specify one or more temporary variables, each followed by an optional new name in parentheses.
  • The optional names must be valid variable names.
  • If new names are not specified, CSCOXREG uses the default names.
  • The optional variable name must be unique. If the default name is used and it conflicts with existing variable names, then a suffix is added to the default name to make it unique.
  • If a subpopulation is defined on the DOMAIN subcommand, then SAVE applies only to cases within the subpopulation.
  • Aggregated residuals are residuals aggregated over records with the same ID value. If ID is not specified, aggregated residuals are not available and a warning is issued if they are requested. The aggregated residual for a subject is written in the last case (or first case if it is easier) of that subject.
  • If time-dependent covariates defined by TIME PROGRAM are included in the model, the following options are not available: MARTINGALE, DEVIANCE, COXSNELL, AGGMARTINGALE, AGGDEVIANCE, AGGCOXSNELL, SURVIVAL, LCL_SURVIVAL, UCL_SURVIVAL, CUMHAZARD, LCL_CUMHAZARD, and UCL_CUMHAZARD. A warning is issued if they are requested.
  • In situations when rootname is needed, the rootname can be followed by a colon and a positive integer giving the maximum number of variables with the same rootname to be saved. The first n variables are saved. The default n is 25. To specify n without a rootname, enter a colon before the number.

SCHOENFELD(rootname:n). Schoenfeld residual. A separate variable is saved for each nonredundant parameter and calculated only for noncensored observations. The default variable name is Resid_Schoenfeld.

MARTINGALE(varname). Martingale residual. The default variable name is Resid_Martingale.

DEVIANCE(varname). Deviance residual. The default variable name is Resid_Deviance.

COXSNELL(varname). Cox_Snell residual. The default variable name is Resid_CoxSnell.

SCORE(rootname:n). Score residual. A separate variable is saved for each nonredundant parameter. The default variable name is Resid_Score.

DFBETA(rootname:n). DFBETA. A separate variable is saved for each nonredundant parameter. The default variable name is Resid_DFBETA.

AGGMARTINGALE(varname). Aggregated Martingale residual. The default variable name is AggResid_Martingale.

AGGDEVIANCE(varname). Aggregated Deviance residual. The default variable name is AggResid_Deviance.

AGGCOXSNELL(varname) . Aggregated CoxSnell residual. The default variable name is AggResid_CoxSnell.

AGGSCORE(rootname:n). Aggregated Score residual. A separate variable is saved for each nonredundant parameter. The default variable name is AggResid_Score.

AGGDFBETA(rootname:n). Aggregated DFBETA. A separate variable is saved for each nonredundant parameter. The default variable name is AggResid_DFBETA.

XBETA(varname). Linear combination of reference value corrected predictors times regression coefficients. The default variable name is XBETA.

SURVIVAL(varname). Survival function. For one-time input data, it is the survival function at the observed time and predictor pattern for each record. For two-time input data, it is the survival function at endtime assuming that the predictor is fixed. The default variable name is Survival.

LCL_SURVIVAL(varname). Lower confidence level of survival function. The default variable name is LCL_Survival.

UCL_SURVIVAL(varname). Upper confidence level of survival function. The default variable name is UCL_Survival.

CUMHAZARD(varname). Cumulative hazards function. The default variable name is CumHazard.

LCL_CUMHAZARD(varname). Lower confidence level of cumulative hazards function. The default variable name is LCL_CumHazard.

UCL_CUMHAZARD(varname). Upper confidence level of cumulative hazards function. The default variable name is SECumHazard.
