Modeling Split Plot DOE results

[#1]

Generalized regression does not work with random effects like whole plot factors so, as random noise cannnot be removed, guess genreg can't be used to model split plot DOE results ?

I suggest you read:

Box, G.E.P., Stephen Jones (1992), “Split-plot designs for robust product experimentation”, Journal of Applied Statistics, Vol. 19, No. 1

I don't find a free version of this paper. JMP GENREG in 1992??
