Relationship between Δ and accuracy in chromosome 6 of T1D study. Illustration of the accuracy obtained in chromosome 6 of Type 1 diabetes data set when change Δ value from 0 to 20. For chromosome 6, in each trial, all the 3504 samples of both control and case were randomly divided into 10 equal partitions. For each of the 10 partition groups, we selected one of them as testing set and the remaining nine of them were considered as training sets. 10 trials were considered and the results were collected based on this 10-fold cross validation procedure. This figure was drawn based on one of these ten trails when the highest accuracy (accuracy refers to the percentage of correctly classified samples over all test samples) was obtained. X axis refers to Δ value, it increases from 0 to 20. Y axis refers to the accuracy obtained in chromosome 6 when using our method, it fluctuates when different Δ values are applied and the highest accuracy is obtained when Δ is equal to 10.56.
