I think you got exactly what you want. In the cox-model, the estimated survival curve will be a step-function. It only jumps where you have an observed event. Therefore, if you have the estimated survival probability for the left limit of an interval, then that estimate the survival probability for the whole interval. ... View more

Thank you sooooooooooo..much! I changed the name "type" to the corresponding variable name in my data. It is working now. Much appreciated! ... View more

Thank you! My project is very time-limited, so I tried different ways by myself and found that if I excluded one predictor, the score node could work. It is odd, but it works. ... View more

Oh, I have solved the problem. The time ID variables got reversed, that is, start_date has been set as end date, and end date has been set as start date. It is odd. I have changed it and now it is working. ... View more

Thanks a lot!!! It is good to know. I will explore these. How about using survival data mining in SAS E-Miner? Because I did not use logistic regression...., but I think that the method used in survival data mining is a kind of logistic regression... ... View more

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:   Usage Note 33307: Scoring (computing predicted values) for new observations or a validation data set http://support.sas.com/kb/33/307.html   and   Techniques for scoring a regression model in SAS http://blogs.sas.com/content/iml/2014/02/19/scoring-a-regression-model-in-sas.html   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. 😉   Cheers, Koen ... View more

Yes, that macro code is from Paul Allison. Thanks for your answers, anyway! ... View more
