Hi Helmut!

You have:

❝ When I set up FA0(1) in PHX’ LME I got…

❝ ERROR 11021: Variance matrix is not positive definite in QA.

❝ Now for the surprise: PHX’ BE-model (which supposedly sits ‘on top’ of LME) converged without a warning. I got

PE 101.0213% (90% CI: 80.7733–126.3450%) s²_WR 0.42100 (CV_WR 72.35%)

… matching Shuanghe’s and your’s in SAS with FDA’s FA0(2)-parameterization.

❝ After exclusion of incomplete data (subjects 8, 14, 17, and 31)

PE 91.2423% (90% CI: 74.0705–112.3950%) s²_WR 0.40652 (CV_WR 70.82%)

… different to yours’.

I was able to run both LinMix and Bioeq in Phoenix and their results matched. Also when I excluded the four subjects with incomplete data, I got:
PE= 90.503 90% CI: 73.561–111.347
so the same as what Detlew posted in his next post with the SAS results. I emailed you a project.
