All,

I have some data for for subjects which includes repeated administrations
of the MMSE (a test of mental status that is usually considered a
continuous variable) and repeated lab values (see below);


ID   Lab value a    Lab value b    MMSE
1         #         #      #
1         #         #    #
1
1         and so on...

2
2
2

3
3
3

4
4

I want to see if the MMSE scores vary in any systematic way with the lab
values.  Note that there are some subjects with 4 observations, some with
3, and some with 2.

I essentially want to do a repeated measures multiple regression, with MMSE
as the outcome variable.

Is there such a thing?

Thanks,

Jim Seward
