re: st: Clustered dataset question

[David Airey <david.airey@vanderbilt.edu>]

For the threshold of interest there is no doubt a population threshold 
around which there is variation due to individual differences. For 
traits influenced by multiple genes and environmental sources of 
variation (like perception), this will always be a reasonable 
description. Try a nested model of some kind, maybe "nlogit"?
