列联表

Taking into account the ordinal character of variables ,statistical inference for bidirectionally ordinal square contingency tables with missing data is studied by proposing a loglinear model with restrictions.

在充分考虑分类变量有序性的前提下，通过建立有约束的对数线性模型研究有缺失数据的双向有序方列联表的统计推断问题。

The essay suggests that the method of estimating coefficient by clustering effect shall be applied in the analysis on service index of railway passenger traffic, then the results and the public information method based on contingency table shall be mutually confirmed to estimates and optimizes the clustering technology.

提出在铁路客运服务指标分析中，采用聚类效果测度系数方法，并将结果与基于列联表的公共信息方法相互印证，评价并优选聚类技术。

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。
