Oh ye mighty caveman,

❝ Note: You might have to switch to an all fixed-effects model in SAS and Phoenix/WinNonlin.


Interesting. I am not extremely well versed with either package but am curious to learn why this would need be done. Could you explain a little, please?
Is it a convergence/optimizer thing? And would it in SAS be something other than PROC GLM cf. the bogus statement?

Muchas gracias.

Pass or fail!

The true Enlightenment thinker, the true rationalist,
never wants to talk anyone into anything.
No, he does not even want to convince;
all the time he is aware that he may be wrong.    Karl R. Popper
