From: Detecting horizontal gene transfer: a probabilistic approach
Performance comparison between χ2 and Chernoff approach for SI-based HGT detection under real biological data. Both the Chernoff-based approach and the χ2 approach for HGT detection were applied on real biological data set contains 1229 pair of closely related species from Eggnog repository. Each point represent a pair of species. The X axis is the SI similarity among the pair. The Y axis is the proportions of the number of HGT-genes detected by the χ2 approach divided by the amount of genes detected by both of the approaches (i.e., high value in the Y axis represents more genes detected by the χ2 approach then by the Chernoff approach. The yellow line represent the boundary between the two cases)
