For a simple paired ttest by regression this requires one indicator or dummy variable for the left and right comparison, plus one indicator for each animal (one less if the program doesn't drop one by itself). So in tpsRegr, my independent variable file would have 1 + n-1 = n vectors of 1s and 0s (or whatever coding scheme I choose), plus the stuff at the file top you show in your help.
Thanks for the pointer. I did not realize tpsRegr in this way can do any general linear model. -Dave On Oct 30, 2005, at 11:18 AM, morphmet wrote: > The tpsRegr program is very flexible and can handle such > designs both as a standard least-squares analysis or by a > permutation test.
