Dear All, I get error while using SAEM estimation method for repeated time to
event model. But, the same model runs well with LAPLACE. Could you suggest what
I am missing below.
This $EST runs well$ESTIMATION MAXEVAL=999 METHOD=COND LAPLACE LIKE PRINT=1
Following $EST method fails with the following error $EST METHOD=SAEM LAP LIKE
NBURN=1000 NITER=1000 PRINT=200 IACCEPT=0.2 CTYPE=3 CINTERVAL=10 $EST
METHOD=IMP LAPLACE CTYPE=3 CINTERVAL=1 NITER=300 IACCEPT=0.2 DF=6 SEED=123
Error (WARNING 121) INTERACTION IS IMPLIED WITH EM/BAYES ESTIMATION METHODS
AN ERROR WAS FOUND IN THE CONTROL STATEMENTS.
545 $ESTIM: "INTERACTION" CANNOT BE USED WITH "LIKE" OR "-2LL".

Error with SAEM and LIKE Option
Hi Varun,
You might try explicitly using “NOINTERACTION” with SAEM and IMP.
Cheers… Brian
