RE: covariate selection question

From: "Joern Loetsch" j.loetsch@em.uni-frankfurt.de Subject: RE: [NMusers] covariate selection question Date: 17-Jan-2006 09:29 Mark, thank you very much indeed. Now, I am still a bit uncertain. One, as you suggest, I could the covariate leave in, which is supported statically. Two, I could it leave out because it does not convincingly improve anything and moreover, it is Weight on F, which is not very helpful anyway. So I tend rather to leave it out. Because I am going to publish the staff, I wanted support to be at ease with the covariates selection that is going to be published and to avoid the taste of randomness or biased selections not supported by statics in the publication. Thank you again Regards Jrn _______________________________________________________ Prof. Dr. med.
