The ICLIFETEST Procedure

Output Data Sets

OUTSURV= Data Set

You can specify the OUTSURV= option in the PROC ICLIFETEST statement to create an output data set that contains the following columns:

  • any variables that are specified using the BY statement

  • any variables that are specified using the STRATA statement

  • any variable that is specified using the TEST statement

  • LeftBoundary and RightBoundary, the two boundary variables that represent a Turnbull interval

  • SurvProb, a variable that contains the survival function estimates at RightBoundary

  • FailProb, a variable that contains the failure probability estimates at RightBoundary

  • IMStderr, a variable that contains the standard errors that are estimated by using multiple imputations

  • BTStderr, a variable that contains the bootstrap standard errors

  • ConfType, a variable that contains the name of the transformation applied to the survival time in the computation of confidence intervals

  • LagrangeMult, a variable that contains the Lagrange multiplier statistics for checking the Kuhn-Tucker conditions

  • SurvProb_LCL, a variable that contains the lower limits of the pointwise confidence intervals for the survival function, using imputation standard errors

  • SurvProb_UCL, a variable that contains the upper limits of the pointwise confidence intervals for the survival function, using imputation standard errors

  • SurvProb_LCL_BT, a variable that contains the lower limits of the pointwise confidence intervals for the survival function, using bootstrap standard errors

  • SurvProb_UCL_BT, a variable that contains the upper limits of the pointwise confidence intervals for the survival function, using bootstrap standard errors

OUTSCORE= Data Set

You can specify the OUTSCORE= option in the PROC ICLIFETEST statement to create an output data set that contains the following columns:

  • any variables that are specified using the BY statement

  • any variables that are specified using the STRATA statement

  • any variable that is specified using the TEST statement

  • Score, a variable that contains the scores for each subject

  • ScoreType, a variable that contains the name of the weight function for which the scores are calculated
