Dan:
If you type -help anova-, than you can find at the bottom a link to
-help anova_postestimation-, which in turn leads to many good stuff,
and among those is -help adjust- which has a description saying
``adjusted predictions of xb or exp(xb)''. It may be a bit cryptic but
the marginal means are the sum of chosen values of x multiplied by the
estimated parameter. This sum, or marginal mean, is often called xb,
after the matrix multiplication that creates this value.
