Problem Note 20857: The OUTPUT data set in PROC PHREG contains incorrect survival estimates
for time-dependent covariates
When the OUTPUT data set in PROC PHREG is enabled using the counting
process style of input (MODEL (START, STOP) syntax) for time-dependent
covariates, the survival estimates produced in the OUTPUT dat set are
incorrect.
There is no circumvention for this problem.
