Through the multiple stepwise regression analysis, the duration of the disease and serum GH level were the main influencing factors of acromegalic cardiomyopathy. 2 Ejection fraction and fractional shortening, were decreased, compared to control group, they still remained in normal range. 3 Isovolumic relaxation time and E wave descending time, were delayed apparently compared to control group, indicating the damage of cardiac relaxation. 4 Subgroup analysis in acromegalic: The comparison between patients with diabetes mellitus and impaired glucose tolerance and patients without DM/IGT showed that there was no significant difference in terms of the parameters in the two groups, in spite of an mild increase of IVST in the former group.

经多元逐步回归分析，病程和血清生长激素浓度为心肌肥厚的主要影响因素。2实验组射血分数和左心室短轴缩短率虽较对照组低，但仍在正常范围。3实验组左心室等容舒张时间和二尖瓣减速时间较对照组明显延长。4实验组中继发糖尿病／糖耐量减低组与非DM/IGT组进行比较，前者仅室间隔有较明显增厚，其余各项参数2组间差异均无统计学意义。

We studied China and fluctuation in business cycle with statistical methods for the first time roundly and systematically, including coefficient correlation, linear regression, turning point coefficient, autocorrelation coefficient, grey system theory, VAR and time series analysis.

第一次全面系统运用统计学方法研究我国经济周期波动，包括相关系数法、一元和多元回归、转折点系数检验、自相关系数检验、灰色关联度、VAR向量自回归和确定性时间序列等方法，第一次把灰色关联分析方法应用于经济周期波动研究。

Radioimmunoassay was used to measure the levels of Leptin NPY Insulin, NO was indirectly calculated by direct measured the level of OD value. M-model echocardiography was examined in all patients, LVMI were calculated by the formula of Devereux , which was recommended by American society of Echocardiography .

This paper made an empirical research on the cause that the Chinese agricultural products faced the TBT through the method of econometrics and multivariate statistics.

文章运用计量经济学及多元统计学的方法，对我国农产品遭遇技术贸易壁垒的原因进行了实证分析。

First, the background, significance and research methods of this paper are introduced, the convergence theory and economic growth difference theory are also introduced tersely.

本文首先介绍论文的选题背景、意义、研究方法及思路；介绍经济增长的概念，经济增长理论及经济增长差异理论相关内容；然后，以统计学的方法描述广东省地区经济增长差异的状况、揭示形成这种状况的直接原因，然后运用计量经济学和多元统计学等多学科知识，借助SPSS、EVIEWS和SAS等统计软件，定量测定了影响经济增长的各因素对广东省不同地区经济增长的贡献程度，从而找出影响地区经济增长差异的原因；接着对广东省各地区经济增长差异的收敛性进行了实证检验，并预测了广东省地区经济增长差异的发展趋势。

It utilized factor analysis and regression analysis ofthe multi-statistics to make the quantitative analysis on a great deal of core proxies in the North Indian Ocean and Indonesian Archipelago areas, and acquiredthe exact conversion relations of paleoceanic environment parameters (sea surface temperatureand salinity) and proxies. Then it made the change curve which can show the changes of paleo-ceanic environment parameters (sea surface temperature and salinity) which followed the changesof depth and provided the contrast between paleoceanic environment parameters of different coreson the landscape orientation. This paper supplied a more scientific and exact method for resumingthe paleoceanic environment on paleoceanography research.

本文阐述了以古海洋学数据库系统数据为基础的古海洋学多元统计分析模型，利用多元统计学中的因子分析和回归分析技术对北印度洋以及印尼多岛海地区大量岩芯的替代指标做定量分析，求出古环境参数与替代指标的精确转换关系，从而做出各岩芯处古环境参数随深度的变化曲线，提供不同岩芯在横向上的古环境参数对比，为古海洋学研究中恢复古环境提供了一种更科学更精确的方法。

Also, the establishment of logistic regression model proves that the choice of stock delivery valuation methods doesn't vary greatly by political affairs and cost of contract, while the establishment of multiple linear regression model bears out that there is a statistics significan ce between accounting evaluation, accounting profession judgment from listed companies' non-circulating assets value depreciation and reflux and the scale of major business income and the relation of high and low ratio of debt to equity. Yet, there is no statistic significance between the relationship of the publication of interest encouraging plan and company establishment date.

在此基础上，本文抽取了实施新会计准则体系之前2005年我国上市公司样本，通过建立有序分组的线性趋势检验模型研究证实，以0.05为显著水平，我国上市公司存货收发频繁程度与发出存货计价方法简化程度之间，并不显著存在一般认为应有的线性关系，排除了发出存货计价方法选择这一混杂因素的影响；进而，通过建立logistic回归模型证实，发出存货计价方法的选择也并不显著受政治和契约成本的影响；通过建立多元线性回归模型证实，上市公司对非流动资产减值的会计职业判断，与其主营业务收入的规模和负债权益比率的高低之间的关系有统计学意义，与是否公布股权激励计划和公司成立时间之间的关系没有统计学意义。
