Dear Statalisters,

I have the following problem using an ANOVA analysis (output see below).

In the further course of analysis I would like to continue calculating
with the "P" Value of the F-Statistics of the ANOVA analysis.
Having a look at the Stata showed me that a whole bunch of values are
stored in scalars, however, as it seem not the P Value?

Is there any way to obtain the P Value in a scalar after an anova analysis?

Many thanks!
Best regards
Christian
