Hi ElMaestro,

» » 3. 2 group parallel
» »    Only the pooled (total) s²p. With a tricky mixed-effects model you

» This tricky model […] 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.

KISS. You are absolutely right. :-D

Cheers,
