Popular multivariate visualization such as scatter plot matrix,parallel coordinates,star plot,Andrews plot have long history and widely application,but a united theoretical basis is absent up to now.

The spearman correlation coefficient was 0.308 (P＜0.01) between serum proinsulin and risk factors score, and the partial correlation coefficient was 0.2095 (P＜0.01) after adjustment for age, sex, body mass index and waist circumference. The results of non-conditional univariate Logistic regression and multivariate stepwise Logistic regression indicated that serum proinsulin level associated with cardiovascular risk factors aggregation, and the odds ratio (95％ CI) was 1.656 (1.483～1.851), 1.652 (1.475～1.850)(p＜0.01) respectively.

Spearman相关分析及调整年龄、性别、体重指数与腰围后的偏相关分析结果显示，胰岛素原水平与危险因素评分的相关系数分别为0.308与0.2095(P值均为0.000)；单因素及多因素Logistic回归分析显示，胰岛素原的水平与心血管危险因素聚集显著相关，其OR值(95％可信区间)分别为1.656(1.483～1.851)、1.652(1.475～1.850)(p＜0.01)。

As we know, multivariate regression and linear partial least square are two common methods for QSAR study.

多元回归法、线性偏最小二乘法是研究定量构效关系常用的两种方法。

Since the concept of NA have a lot of applications in multivariate statistical analysis, reliability theory and percolation theory, various aspects of NA are significant and have been investigated by a host of scholars Fist, we give some Fuk-Nagaev type probability inequalities, moment inequalities of maximal partial sum for sequence of NA random variables, and some strong law of large numbers and complete convergence for sequence of NA random variables are obtained.

在本论文中我们对不要求强平稳或同分布的NA随机变量列进行了多方面的研究：首先对NA列建立了一组具有NA特点的关于最大部分和的Fuk-Nagaev型概率不等式及其关于某一类特定函数的矩不等式，它们在后续给出的极限定理的证明中发挥着重要作用；研究了具有不同分布的NA列的强收敛性，如对NA列建立了更一般条件下的Wittmann型强大数律及完全收敛性，同时也进一步改进了R。
