Comparison of RGLM based feature selection method with the RF based method of Díaz-Uriarte et al. For each data set in the 20 disease gene expression data, the RF based variable selection method by Díaz-Uriarte et al selects a small set of genes. For each of the selected genes, the file reports the ranking in terms of the RGLM variable importance measure timesSelectedByForwardRegression. As expected, only a few of the selected genes have a high rank in terms of timesSelectedByForwardRegression illustrating that these variable selection methods are different.
