Subject: The u^2 coefficient in c on (e,u,u*e,u^2) does NOT distinguish among<br> the four subset x MoSS roll-ups
Here are the average t and p values for u^2 for each value of subset x

Moss | (Fold,Set,Len) = (all,all,all)

--------------------

subset

x u^2

Method t p

SxN 35.17 0.457

SxC 38.19 0.416

SxR 36.88 0.434

SxC 34.69 0.438

--------------------

I think you?ll agree from these numbers that this coefficient is

useless for distinguishing between the four subset x MoSS

combinations, and that we can therefore adopt the c on (e,u,u*e) model

instead. But if you want to see the 1179 rows of detail data for u^2

underneath the above four roll-ups, let me know and I will send it

along.

Also, just out of curiousity, I will run the same analysis for the u*e

coefficient of c on (e,u,u*e) and post back the results.
