Embodiment Construction
[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0051] 1. Use data in the form of 0, 1, and 2 to represent genotype data. For example, the data of SNP genotype AT is represented as follows: AA is represented by 0, TT is represented by 2, and AT / TA is represented by 1. figure 2 11 SNPs are shown (SNP A ~SNP K ) corresponding to the genotype data of the 4 samples, the last column Class represents the phenotypic traits, where Class=1 represents the case (disease), and Class=0 represents the control (control). In order to improve the calculation efficiency of subsequent conditional mutual information between nodes and Bayesian network scoring, th...
