Using the TIMELIST= option on the PROC LIFETEST statement in conjunction with the CONFBAND= option on the SURVIVAL statement in writes incorrect survival estimates and standard errors to the Product Limit Estimates table in PROC LIFETEST. The SURVIVAL OUT= data set is not affected. There is no work-around other than ommitting either the TIMELIST= option or the CONFBAND= option. In SAS9.2 the options on the SURVIVAL statement, including CONFBAND=, have migrated to the PROC LIFETEST statement and this problem does not occur.
