Authers: Sahar Noori1, Keramat Nourijelyani 2*, Kazem Mohammad3, Mohammad Hossein Niknam4, Mahdi Mahmoudi5, Laris Andonian6, and Arash Akaberi7

Abstract: Technology advances in this century, especially, in molecular generics yields high volume, high dimensional data. This creates many unprecedented challenges for statisticians who are responsible for analysis of such data. Although logistic regression method is quite popular in association analysis in medical researches but it has some serious limitations in handling high dimensional data. In present study, our goal is introduce a modern model-free statistical method called random forest that we believe is able to overcome difficulties ... سال انتشار: 2012
