Re: [R-sig-phylo] summary stats for comparative methods p-values

I can think of 2 better methods: 1. Bayes. Sample from the set of 100 trees, used as a prior on the "true" tree structure (assuming they are a true posterior set, as Joe points out). See: de Villemereuil et al. BMC Evolutionary Biology 2012, 12:102 http://www.biomedcentral.com/1471-2148/12/102

If the 100 trees are trees sampled from a Bayesian posterior, or else trees from bootstrap samples of your data, then you might just take the estimates from each tree (say estimates of a regression coefficient). Consider their distribution and ask whether the null hypothesis value (such as having

Alternatively, the proportion of trees that gave in a significant result (for a given threshold) could be of interest. It depends on your question. Simon Simon Joly, Ph.D. Chercheur, Jardin bo

Darrin, list- I'm sure there's people on this list with better answers, so I'll throw in first with what might be the wrong answer (but feels right to me), and say you more or less need to report all of them: like, show a full histogram of the p-values. At least, as a reviewer, that is what would

[R-sig-phylo] summary stats for comparative methods p-values

2016-03-10 Thread Darrin Hulsey
I am running a series of statistics on a subset of 100 trees that returns 100 different p-values. I was wondering what the best way to report summary statistics for these 100 p-values would be (median?, measure of variance in all 100 p-values?). Thanks for any insight.
