	--Your problem is that you don't read or pay attention to my

papers. I do treat within county correlations, and I never assume anything

is linear except between radon and lung cancer which is the theory I am

testing. Why not read my paper on "Treatment of confounding factors in an

ecological study" whiich is posted on my web site before expounding on

your criticisms? Why not submit your suggestions in a letter to the

Editor, which, if accepted, will automatically get you a $1000 reward?
