Hi all,
I've got a nested ANOVA model, and I am trying to do a post hoc comparison
of the means of the factor within each nest.  I haven't found a way to get
SAS to calculate any of the standard tests (SNK, Scheffe, etc).  Is there
an easy SAS command that will do such a thing, or should I start
coding it myself? The code below works for non-nested models.

I'm under the impression that comparing the means within each nest is
valid statistically (cf. Hicks "Fundamental concepts in the design of
expts." 4th ed, p183).

Any comments would be greatly appreciated.

Dieter
