Relationship between Δ and accuracy in Chromosome 14. Illustration of the accuracy obtained in Chromosome 14 of Parkinson disease genome-wide data set when change Δ value from 0 to 3. For Chromosome 14, in each trial, all the 541 samples of both control and case are randomly divided into 10 equal partitions. For each of the 10 partition groups, we select one of them as testing set and the remaining nine of them are considered as training sets. 10 trials are considered and the results are 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) is obtained. X axis refers to Δ value, it increases from 0 to 3. Y axis refers to the accuracy obtained in Chromosome 14 when using our method, it fluctuates when different Δ values are applied and the highest accuracy is obtained when Δ is equal to 0.8.
