Thank you Patrick for your thoughts.
I was expecting someone had written a function that does maybe a
hierarchical comparison of var-covar matrices using the flury hierarchy
as proposed by
Philips and Arnold in Evolution 53(5), 1999;1506-1515. But your email
has an interesting idea, so I will t
My first thought is to use a random permutation test.
In this setting the main question you need to ask is
what distance measure do you want to use between
variance matrices -- there are lots of choices. One
that I've found useful is the absolute value of the
maximum eigenvalue of the difference o
Hi,
Using package gclus in R, I have created some graphs that show the
trends within subgroups of data and correlations among 9 variables (v1-v9).
Being interested for more details on these data I have produced also the
var-covar matrices.
Question: From a pair of two subsets of data (with 9 vari
