Thanks, Lee. Your reply is most helpful, and I wonder whether I was misquoting Dan in my previous email (gosh perhaps it was Les or Mike).
OK, I see your argument for preferring -0.1 over -0.25, but I guess one would have more confidence in the pattern if recovering the same pattern in both cases, agree? And, much moreso if both phenograms agreed with an SSH ordination of the same data, right.
Though, I do wonder what you would do, Lee, if you had a -0.25 phenogram agree in detail with an SSH ordination but somewhat disagree with a -0.1 phenogram. I would still go in favour of the congruence between analyses. How about you (or is this to hypthetical for your liking)?
