[R] Confidence interval for relative risk

[Spencer Graves]

      When I have refereed manuscripts for publication and have been 
unable to get their answers, I have told the authors they need more 
explanation of their methodology -- while summarizing what I tried in a 
few lines.  I've even told some that it would make it vastly easier for 
the referees and increase the potential readership for their article if 
they make R code available -- at least downloadable somewhere and 
preferably in a contributed R package, where it could attract interest 
in the article from audiences who would not likely find it any other 
way.  I've done this for articles that were NOT written to specifically 
describe statistical software. 

      I have not followed all of this thread.  However, one suggestion I 
saw looked like it used the "delta method", if I understood correctly 
from skimming without studying the details carefully.  Have you also 
considered 2*log(likelihood ratio) being approximately chi-square? 

      Just my 2e-9 Euros (or 2e-7 Yen or Yuan).
