Odds Ratio MDR

A version of our Multifactor Dimesnionality Reduction (MDR) method that uses odds ratios to determine high-risk and low-risk genotype combinations prior to constructuve induction is available as a package for R called ORMDR. I haven't had time to try it. Let me know if you like it or find it useful.

Here is the paper that describes this approach:
