A concrete type I/III Sum of square problem
Hi R-help members,
I have read a lot in the Archive about the "Type I" vs "Type III" sum
of square. I think I have read confusing post so
I want to have a clear idea of the problem.
Here is an example.
I have 3 groups of subjects of unequal sample size (G1 (n=7), G2
(n=7), G3 (n=4)).
for Each subject I have 4 measures corresponding to the crossing of
2 factor (A & B)
