Re: [R-sig-eco] repeated measures with multivariate data

2010-07-25 Thread Peter Solymos
Hi Kay, I meant to make permutations within time points, i.e. strata=time, and not within locations (strate=locations). adonis do F-tests based on sequential sums of squares from permutations, thus the non independence of repeated measures can have an effect on p-values associated with terms subseq

Re: [R-sig-eco] is 1 hour long enough to assume independance?

hi chris, I think you are not quite giving us enough information to assess this situation. Otherwise, I´d think that any data coming from ONE dingo (i.e. one radiocollar) will never be independent, the 1 hour is not the problem. Or can you tell otherwise? gab On 7/21/10 3:52 AM, Chris Howde
