Re: Cohen's Fallacy

["Rad health" <healthrad@HOTMAIL.COM>]

I read the papers and I agree with Field, that you are confusing individual 

level confounding with group level confounding.  Why not follow Field's 

suggestion and examine the source of the group level confounding?

You have no basis for guessing what the group level confounding is by 

assuming it is the same as individual level confounding.
