Hi Klaas and Jean, Thanks a lot for your immediate response and input. I will definitely test that whether having IOV on F1 will help. But I have a more general question about IOV. Can you comment on having one IOV in the model versus having five different IOVs across five different occasions? Is i

Claire, It is the traditional assumption that BOV variance does not change with occasion (an assumption implemented with the SAME option). But it would be quite reasonable to look for BOV variance that is different from occasion to occasion eg. BOV in F might be relatively low soon after star

Dear All, We are using psn version: 3.4.2 together with NONMEM 7.2.0 on a Linux Sun Grid Engine (SGE). When using multi-cores run on SGE, it happens sometimes that NONMEM returns a log file where the "MONITORING OF SEARCH" starts and nothing is reported. Looking into the psn directory, I fou

Pascal: I cannot help regarding having all console messages sent to the proper files in the PSN environment, but I can assist in avoiding your present NONMEM error. If you insert at the beginning of the control stream file $SIZES LIM1=?? and insert a large enough value for ??, then file buffer 1

Hi Nick, Thank you a lot for clarifying how to incorporate BOV in the model. I tested BOV on F1 with the same option as well as variable BOVs on F1 from different occasions. But either of them improved the fitting. Actually according to the results from non-compartmental analysis, AUC0-inf are very
