RegisterDegrees of freedom 3-period full replicate [RSABE / ABEL]
Dear Detlew,
I didn't try the code, so it was only what I expect in result (my mistake - I didn't write that for 2x2x3 replicate design I thought to filter data to only those used in GLM).
For 3-period 2-sequence replicate design with R replicated only in one sequence I would use code:
(Instead of the code which I copied from EMA Q&A in my previous post. I think there is no reason to have sequence in the GLModel for this case. And I am used to see degrees of freedom in ANOVA table which are giving us with real number of cases in evaluation: (number of subjects in evaluation-1) and (number of values in evaluation-1) in total)
In the example, due to we have 35 subjects in sequence with replicated R, I am expecting:
However, it does not affect anything important.
But if 72+1+34 results in total 108 (similar as 2+2=?, I think 5 is a very very good estimate, ... in accordance with the principles of doublethink "Sometimes they are five. Sometimes they are three. Sometimes they are all of them at once"), I have no power to know (same as Winston Smith has).
Btw. you are right about I did not include balance/unbalance option to table of dfs in my previous post (so it's true only for cases with no dropouts there).
