查询词典 correlations

It is interpreted that the correlation structure of the allelic polymorphism data contains null correlations introduced by "closure" and the statistical distribution of the data is not normal because of its constant row sum,which resulted in great difficulties in analyzing the data with traditional multiple linear statistical methods such as principal component analysis,factor analysis,cluster analysis and canonical correlation analysis.

通过运用BEKK模型模拟的数据，本文比较发现，Sequential-BEKK模型在进行样本内预测相关系数矩阵时，表现优于BEKK系列模型和OGARCH模型，稍差于CCC和Dec模型，但是Sequential-BEKK能够比其他模型更好的刻画相关系数的动态过程。

In gastric carcinoma tissues, no correlations of TNFR Ⅰ and Ⅱ expressions with serous membrane invasion or lymph node metastasis were found, but the differentiation grade was positively correlated with TNFR expressions (r=-0.3111, P=0.035; r=-0.5952, P=0.000, respectively).

在胃癌组织中，TNFRⅠ、Ⅱ表达与和浆膜浸润和淋巴结转移无关，而与肿瘤分化程度有关(r=-0.3111，P=0.035；r=-0.5952，P=0.000)，当肿瘤分化程度低时TNFRⅠ、Ⅱ表达低。
