Hi ElMaestro,

❝ ❝ If I trust Wikipedia

❝ ❝ (s²₁+s²₂)²/[s⁴₁/(n₁–1)+s⁴₂/(n₂–1)] = 11.64240178 (≠ 10.75546079) :confused:

WP is a strange piece of cake. The formula was correct on 2013-04-16,

an anonymous editor from Austin, Texas screwed up on 2013-06-27,

I love audit-trails.

❝ 10.76 appears correct.

In the meantime I have edited my post…

❝ Quickie:

Nice.

❝ But I have to admit I am still one big question mark as to why all this works correctly. All the matrix explanation and stuff is rather gibberish to me. I looked up what SAS writes about DDFM=SATT and I felt like hitting myself with a hammer after reading two lines of it.

You are not alone.
