Hi Hötzi,

» 3. 2 group parallel
» Only the pooled (total) s²_p. With a tricky mixed-effects model you could
» get s²_pT and s²_pR.

2 group parallel: This tricky model may not be so tricky after all, but may be overkill. I believe you will get the same result as you would obtain from doing a plain sample standard deviation on T and R subsets, respectively.
