Re: beta values


Hi Lee and Jeremy (and others)

I’m glad there has been some discussion on beta values. I often try out extreme beta settings (plus some in between) to see how the dendrograms re-arrange themselves, then look for a congruence between them and the ordination, but I’m only working with small data sets. I tried switching to groups to compare the two types of analyses and this made it easier. The only minor difficulty was comparing the allocated names of the groups. The dendrogram uses the farthest branch for each group name, but the SSH uses consecutive numbers. If it used (as an option) the label closest to the centroid instead, it might be a bit easier to compare to the dendrogram group names. I’m not sure – just a thought.
