Hi, I'm using JMP Pro 11 with Mac OS X 10.9, and trying to learn how to used the Mixed Model personality. I'm using the Animals.jmp sample dataset, which has 6 subjects, each measured in the fall, winter, spring, and fall. I'm trying to predict miles roamed from species (between subjects) and season (within subjects). JMP crashes ("quit unexpectedly") every time I run this simple Mixed Model:
I'm sorry that JMP Pro 11 is crashing on you that way. It looks like that might be a bug. I'll get our testing group to look into it.
In the meantime, the correct way to specify the model is to use a column that uniquely identifies each subject. In this case, that's the concatenation of Species and Subject, which doesn't exist in the data currently.
The new transform columns options will allow you to create this concatenation on-the-fly though and specify that as the Subject.
Personality( Mixed Model ),
Formula(:species ||" "||Char(:subject ))
Repeated Effects(:season ),
Repeated Structure( Unstructured ),
Run( Random Effects Covariance Parameter Estimates(0))
