I have I and D overlap values for two species MaxEnt predictions and I'd like to now do an equivalency test. I've been able to make several randomizations of the populations and get I and D values for each separate random permutation. I'm just wondering what the next step would be. Can I test my observed I and D values from my actual data to the distribution of the I and D values of these random permutations? I've coded this out, but I've tried playing around with a couple of the R packages made for this and that seems to be what they do, but I'm just checking.
