I will see if it can be expanded to FOCE/FOCEI/Laplace for NONMEM 7.4. Robert J. Bauer, Ph.D. Vice President, Pharmacometrics R&D ICON Early Phase 820 W.

And, can you share your $EST step options? Thanks, Bill On 7/17/2016 4:28 PM, Mark Sale wrote: Question: NONMEM has a function to run a grid search to obtain initial estimates for THETA. But, when I try to do this with BQL data/Laplacian I get this run time error message: 0PROGRAM TERMINATED BY OBJ WITH INDIVIDUAL 1 ID= 1.00000000000000E+00 DATA REC. 13 WITH NMPR17, LAPLACIAN ESTIMATION METHOD MUST BE USED It seems the Laplacian isn't used for the grid search for initial estimates (even though specified in $EST). any ideas?
