Table 2 Classification accuracy results obtained by the modified t-test measure for different feature subsets with differen numbers of top ranked features (SNPs) in 30 simulations, on 3 and 4 populations, respectively
From: Effective selection of informative SNPs and classification on the HapMap genotype data
