❝ Took some time to actually find where I could edit my profile, but I did read "the rules". 
Kudos!
❝ ❝ I don’t understand what you mean by incomplete block when you tested three treatments in three periods. Generally in an IBD: treatments > periods.
❝
❝ What I mean is that even though we have 3 periods and 3 treatments, the comparisons are Test 1 vs. Ref and Test 2 vs. Ref. In other words, we "ignore" one period when comparing the two.
Interesting. Search the forum for ‘crippled model’.
❝ […] whoever prepared the guidance…
Eric Ormsby?
❝ … most likely thought about a 2x2 study, where removal of one period "removes" the entire subject from analysis.
Think so. Also ElMaestro’s guess.
❝ […] perhaps it's not our place to try to figure out what the agency was thinking when writing the guidance.
Oh no; this is the place!
❝ We're using PROC MIXED anyways.
So don’t bother.
