Dear community members,   Please advise on this:  I was trying to using PROC GLIMMIX with random intercept, and a "store" command on my training set, and then I want to calculate the prediction using an external dataset (validation set) using PROC PLM with the random effect. I was a little confused, because the "store" command may not be able to save the random effect information. If PROC GLM cannot do this automatically, how would we do it manually?    Thank you in advance!     ... View more

To Community members,   If the predictions the same for the following 2 scenarios with PROC GLIMMIX: 1. fit the model with random intercept and predict with option pred(noblup ilink), suppose to be marginal mean as well? 2. fit the model without random intercept and predict the marginal mean   If not the same, why?   Thank you all!   ...

Dear Community,   I am fitting the conditional logistic model using PROC GENMOD and I want to output the robust standard error for the estimated odds ratio instead of the log(odds).    I know the ods output GEEEmpPEst can output the empirical standard error on the log scale, but I am not sure whether ods output ESTIMATES will output the empirical SE on the OR scale.   Thank you! ...

Dear communities,   I am wondering if anyone can answer this question:   I want to get the weighted Kaplan Meier survival estimation/curve through Proc Phreg with "product-limit" option specified. However, I cannot find the background calculation/formula that SAS used to generate the survival estimation, could you point the paper I can refer to? The weight I am using is the ratio of the 1: M matched (case/control).    Thank you! ... View more
