Registerannoying imbalance [Two-Stage / GS Designs]
Hi all,
Dammit.
I just tried to work out the equations for the various sums of squares. Imbalance on the sequence part (6 in stage 1, 2 in stage 2) implies that I can probably not derive a residual ss by means of a simple formula. Then the only option (at least for me) will be the matrix way forward and that will slow the whole thing considerably down. Might as well just set this up in R then?!?
Does anyone feel like wasting some days and nights on deriving a formulae for residual SS now that I admit algebraic defeat?
❝ – Sequence in Stage (with nesting; we could also just give them factor levels like 1,2,3,4,5,6,7,8 and observe that 1..6 apply to stage 1 and 7..8 apply in stage 2.
