Hello,

There are multiple ways of scoring a new dataset (new observations) using an existing model.

Try using the STORE Statement (in PROC LIFEREG) and subsequently PROC PLM.

The model (fit by PROC LIFEREG) is written to an item store.

An item store is a binary file format that cannot be modified by the user. The contents of the item store can be processed with the PLM procedure.

See here for some background info:

There is also a "SAS Statistical Procedures" section within the Analytics community. You would have got your answer 4 weeks earlier by posting your question over there. 😉
