Relative risk
I didn't add the bit "[t]he log of relative risk is usually taken to have a sampling distribution that has an approximately normal distribution."

It is common to assume a normal distribution for a sampling distribution. I'm not sure how taking the log of a distribution changes things. I suspect it is done 'cause logs are easier to work, i.e. adding two logs is like multiplying the two quantities; it is a hold over from the bad old days without computers (see http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1257309)-- but this could be completely wrong. Did you look at the reference for the statement --http://www.stata.com/support/faqs/stat/2deltameth.html?

Any case, my stats course is a while back, I didn't to a lot of proofs ('cause they aren't terribly practical) and my approach to stats is one of a bricoleur. So, I'm afraid I can't be of much use to you. If you do figure it out-- add it to the article. :) Nephron T|C 17:56, 7 October 2007 (UTC)
