I'm new to clusters analysis and I have to plan one in order to
identify 2 groups of patients who show responsiveness (or not) to a
I had a look on SAS documentation related to Proc Cluster (114 pages!)
but I'm quite bothered because there are many distances which are
proposed. I don't know which strategy I should plan: I think the best
would be to choose the distance leading to the grouping which best fits
with my responsiveness criterion. But this means that I'd have to
identify clusters resulting to each distance and test association with
my responsiveness criterion each time.
Do you know which distances are the most currently used ?
Thanks in advance,
