Fig. 7From: Discrimination between human populations using a small number of differentially methylated CpG sites: a preliminary study using lymphoblastoid cell lines and peripheral blood samples of European and Chinese originRelation between the number of CpG used in a training group and the quality of classification. Upper panel: The value of AUC parameter obtained in the training group (B-cell lines: CEU, n = 10; CHB, n = 10) depending on the number of CpG studied. Lower panel: Precision of sample classification depending on the number of features (CpGs) analyzed in two tested groups: B-lymphocyte cell lines (B1, red color, n = 48) and blood samples (B2, blue color, n = 40)Back to article page
