The main content of preparation before scoring is selection of characteristics, which mainly uses Logistic regression, contingency table analysis and artificial neural network. Personal credit scoring and evaluation mainly uses general discriminant analysis, refined decision tree model, improved genetic algorithm, probability neural network and behavioral scoring model. The effect test of personal credit scoring includes fitting effect test and fitness test. The former involves right prediction rate, Kappa consistency test, ROC curve, and the latter includes likelihood ratio test, Hosmer-Lemeshow test, etc.

Cluster analysis and two-way contingency table analysis were used to study the ontogenetic variations in the feeding habits of plaice, and the results showed that the feeding activity of plaice did not vary significantly among 7 size classes within the size between 51 mm and 370 mm, but ontogenetic variations were found in the diet composition. In the size class 200 mm, plaice mainly fed on Decapoda and fishes.

通过聚类分析和列联表检验等方法对高眼鲽摄食随体长的变化进行研究，结果表明：体长在51~370mm范围内的高眼鲽的摄食强度没有显著的体长变化，但不同体长组摄食的食物种类有一定差异。200mmm的则主要摄食底层虾类和鱼类，磷虾类所占比例减小。

Methods The genotype of 4 SNPs in 108 simple CHD patients and 200 normal people were analyzed by restriction fragment length polymorphism and denaturing high-performance liquid chromatography. The statistical contingency table method was used to analyze SNP genotype frequency and gene frequency in patients and control group;then, the haplotypes were established and their frequencies in the two groups were assessed by PHASE software.

方法应用限制性片段长度多态性和变性高效液相色谱法结合测序，分析108例单纯性先天性心脏病患者及200名正常人4个SNP位点基因型；应用列联表法统计分析患者组和对照组各SNP位点基因型及等位基因频率；应用PHASE软件构建单倍型并统计分析患者组及对照组单倍型频率是否存在差异。
