I'd be happy for simply a reference or even search terms as I feel like this has to be known*.
Suppose we have a known probability distribution $X$ and a fixed integer $n$. I am interested in the following distribution on all the set of partitions of $X$ into n (non-empty, if need be) sets. If $P = \amalg X_i$ is such a partition and $F_P$ is the F statistic for $P$,, can we approximate the p-value for F?
This seems to be a way to define or test whether or not a division of $X$ into groups is meaningful: it is meaningful when the F-statistic's p-value is small. That's why I would think this is known.
Thanks!
I first asked this question yesterday on mathstackexchange here and didn't think it was appropriate since it's not a research related question. However, the suggested question/answers to this on mathoverflow and the little attention I have received on mathstatckexchange suggests this might be a more appropriate site. In either case, I will remove one of the two based on feedback.
