❝ […] (consider upgrading to Phoenix; release 6.4 is expected this summer). My setup in Phoenix / Win­Nonlin 6.3:

❝ ● Group model I:

fixed:  Group+Sequence+Sequence(Group)+Period(Group)+Treatment+Treatment×Group

random: Subject(Sequence×Group)


Helmut: I saw above post focusing on performing studies in a large number of subjects so it is convenient to split the subjects into 2 groups. I created a data set with two groups (2 way crossover study with 2 treatments and two periods and two sequences) to try out above code in Phoenix WinNonlin 6.3 (V6.4 will be available in August).

I tried to set up the model from above, but I found the program rejected the code I put it in (text turns red). I do not know what boxes to check to get the program to accept the code, which includes "Group".

Group+Sequence+Sequence(Group)+Period(Group)+Treatment+Treatment*Group

Please can you advise accordingly,

Angus

To propose that poor design can be corrected by subtle analysis techniques
is contrary to good scientific thinking.    Stuart J. Pocock
