Dear Paolo!

Had a quick look in Phoenix6.1 (average BE, too late to get FDA's model running).
Fixed: SEQUENCE+TREATMEN+PERIOD
Repeated Specification:
PERIOD
Variance Blocking Variables (Subject): SUBJECT
Group: TREATMEN
Type: Variance Components
Random Effects: TREATMEN
Variance Blocking Variables (Subject): SUBJECT
Type: Banded No-Diagonal Factor Analytic (f)
Number of factors (f): 2

I got:
Warning 11091: Newton's algorithm converged with modified Hessian. Output is suspect.
Model may be over-specified. A simpler model could be tried.

and sigma²WR 0.1861995 (CVWR 0.452397)

If I try IBE/PBE I got:
*** WARNING 11121: Subject X had incomplete design and was discarded.
*** WARNING 11122: Sequence RTR had less than two complete subjects and was discarded.
*** WARNING 11122: Sequence TRR had less than two complete subjects and was discarded.
*** ERROR 11107: Fewer than two sequences had complete design. Program termininating.

X in the warning above is the ID of all subjects except ones in sequence RRT. That was it. :confused:

Always listen to experts.
They’ll tell you what can’t be done and why.
Then do it.    Robert A. Heinlein
