❝ I love SAS‘s ‘.’ - Phoenix/WinNonlin spits out ‘Not estimable’, but I can trim it to ‘.’ or even ‘0’… :-D


Dear Helmut,

I decided to continue the topic (moreover Simon kindly directed me here).
Regarding "Not estimable". Could you please share your expirience with following issue? When I use such a model: Sequence+Period+Treatment+Group+Patient(Sequence) I get "Not estimable" in the results of ABE in WNL. Model is wrong? When I delete the "group" than error dissapears. Comments: it is BE cross over study in 3 groups and all effects are fixed.

The difference between a surrogate and a true endpoint
is like the difference between a cheque and cash.
You can get the cheque earlier but then,
of course, it might bounce.    Stephen Senn
