Register… Snow White or Little Red Riding Hood? [General Statistics]
Dear Helmut,
Me too.
I have fiddled a little bit with the expected sequence-by-period means and intra-subject contrasts (A,B,C,D are the treatment effects, p1... p4 the period effects):
Ups! In this parametrization we really have one treatment' parameter and only 2 for the period'.
The pair f.i. A/D is left to you
.
It has one treatment parameter (df=1) and 4 period' parameters which sum to zero (translates into df=3?).
❝ Beyond my intellectual reach ...
