Subject   st: adjustment of diagnostic Likelihood Ratio's for covariates
Date   Sun, 28 Sep 2003 09:05:33 +0200 (CEST)

I want to construct a clinical diagnostic scoring
system with about 8 variables. I would like to use
diagnostic Likelihood Ratios to describe the
multiplicative change in the probability of disease
according to the information of each variable. All the
variables are correlated in some way with the others
and the usual independence Bayes rule is not valid.
How can the LR's be adjusted for the covariance?
