IMO, this *is* a very helpful forum compared to many others.  

The point Rich made quite clearly, I thought, was that you appeared to be using "relative risk" in a very non-standard fashion.  See the Wikipedia page on the RR for examples of how it is typically used.

   http://en.wikipedia.org/wiki/Relative_risk

As you can see there, the RR is typically used in the context of a 2x2 table, not in the context of 23 (or however many) dichotomous variables.  

So, IMO the reason you were not getting the answers you were hoping for was that people were still trying to understand exactly what kind of data you had, and what question(s) you were trying to answer.  If you want clear on-target answers, you have to provide a very clear description of the problem--and *examples* are often very helpful.

HTH.

Dear Rich,


Never mind. I figured it out on my own. I hope this is the right forum for exchanging ideas in a helpful thoughtful manner. It doesn't sound like it.
