Re: st: Testing dependence in a 2x2 table for clustered observations

[Joseph McDonnell <jockmcdock@gmail.com>]

I'm not sure I agrees with Steve here. Maybe I don't understand how he
would stratify, but I can't see that stratification would solve the
lack of independence. Personally, I'd just use the multilevel
approach. Yes, walnut meets sledgehammer...
