Figure 4From: Integrative analysis of single nucleotide polymorphisms and gene expression efficiently distinguishes samples from closely related ethnic populationsTest accuracy and number of genetic markers in the selected classification models in the 10-fold cross-validation procedure. In each of the eight ethnic population combinations, the testing accuracy and the number of genetic markers in the selected classification model in each of the 10-fold cross-validations are shown in the top and bottom panels, respectively. The top and bottom panels show box-whisker plots of the testing accuracy and the number of key predictive markers based on GE-only (green), 500 K-only (purple), Array6.0-only (red), 500 K + GE (orange), and Array6.0 + GE (yellow).Back to article page
