Subject: proc PHREG
I've done a cox regression with time dependent covariates in SPSS and
analyzed the same data using proc PHREG, all settings at default in both
cases. Unfortunately, the two analyses give me quite different results.
Does anyone know why this is, what SAS does differently from SPSS? Thanks
a lot i.a.
