This study conducted a secondary data analysis based on the data from 1999 Survey of Health and Living Status of the Middle Aged and the Elderly in Taiwan, provided by the Bureau of Health Promotion, Department of Health, R.O.C.. The study subjects were elders over 65 years old, and the number of valid samples was 2890. The data were analyzed with descriptive statistics, one-way ANOVA, Chi-square test(X2), Independent-Samples t-test, point biserial correlation, the Pearson product-moment correlation, logistic regression analysis, multiple regression analysis and hierarchical regression analysis.

为此本文尝试着将分位数回归理论引入到回归模型中,通过对我国上市公司的相关数据进行分位数回归分析后发现,不同资产负债率水平下,企业股权结构、企业产生内部资源的能力对资本结构的影响效果不同:低负债率水平下,两者均与债务水平正相关;而高负债率水平下,又均与债务水平负相关。

As one of the leading branches of the modern statistics, the riouparametric regression analysis is widely applied to explore the relationship between the the response variable y and the covariable A'.

对于非参数回归人们提出了许多估计方法,如核估计,局部多项式估计,光滑样条估计,级数估计(傅里叶级数估计,小波级数估计)等。这些方法本质上讲都是局部估计或局部光滑,当回归变量X为一维变量时,非参数回归函数用这些方法一般都能得到很好的估计。

By designing three hierarchical factors of "corporate governance characteristics","medium agent characteristics" and "corporate basic characteristics", we applied a more integrated and systematic approach to study the influencing factors. Besides, our hierarchical regression analysis has more explanative effects.

The results from statistic data analysis using the statistic software SPSS15.0 for descriptive statistics, chi-square evaluation, laddered logistic regression, factors analysis, credibility analysis, variables analysis, and multiple comparison are as follows: I. An analysis of the prominently related variables with whether or not to receive cervical smear screen of tendency factors, enabling factors and needs factors by using the logistic regression model was performed.: 6 variables of tendency factors with predictive value as to whether a woman receive cervical smear screen or not include age, marital status, educational level, family structure, religion, and the knowledge of free smear examination offered by mandatory citizen health insurance; 4 variables with enabling factors with predictive value include average monthly income, district, whether receiving telephone or letter notices in the past year, and the degree of convenience of the examination location. One variable of needs factors with predictive value: is the suitability of the examination time notified. The accuracy rate of laddered logistic regression model built by this research was 74.1%.

利用统计软体SPSS15.0进行描述性统计、卡方检定、阶层式逻辑斯回归、因素分析、信度分析、变异数分析、多重比较等统计方法分析,根据统计资料分析结果:经卡方检定后,将倾向、能用、需要因素中具有显著相关变项与是否接受抹片检查,放入逻辑斯回归预测模型中,本研究结果发现:倾向因素中的六个变项:年龄、婚姻状况、教育程度、家庭结构、宗教信仰、是否知道健保提供免费抹片检查对受检与否具有预测力;能用因素中的四个变项:平均月收入、地区别、过去一年内是否接到电话或信函通知、收到通知的受检地点是否方便对受检与否具有预测力;需要因素中的一个变项:收到通知的受检时间是否合适对受检与否具有预测力;本研究所建立的阶层逻辑斯回归模型的整体预测正确率为74.1﹪。

同时,引入非线性回归模型之一的指数函数模型,综合应用非线性回归模型的线性化方法和线性回归分析方法,使用了计量经济学软件Eviews3.1和统计学软件SPSS11.5,对民间投资与经济发展的&九大关系&进行实证分析。

The 352 valid samples were analyzed by SPSS. The results showed there was no distinct corresponding relationship between the product attributes and reaction time. The different key attributes from questionnaire importance rating and the shortest reaction time standards were used to regressively analyze the results of customers' overall rating (such as overall satisfaction,objective quality, recommend intention).The results indicated that the coefficiency of regression of the special attributes chosen from reaction time to overall rating was distinct, while the coefficiency of the special attributes chosen from importance rating to overall rating was not. The main conclusions are: 1. Regarded attributes can be obtained by the reaction time of brand performance rating.

本实验的有效样本为352个,通过SPSS软件进行分析统计,数据统计结果显示,在品牌表现评价反应时与其重要性问卷评定结果的相关系数的检验中,并未发现品牌表现评价反应时与品牌属性重要性评定结果之间的显著相关;将由问卷重要性评价最高标准所得到的关键属性与通过品牌表现评价反应时最短的标准所选取的关键属性的品牌表现分别对消费者的总体评价结果(如&总体满意度&、&主观质量&、&推荐意向&)进行回归分析,发现通过品牌表现评价反应时方法选取的特殊关键属性(与问卷重要性评定法选取不一致的关键属性)的品牌表现对总体评价结果的回归系数显著,而重要性评定问卷法选取的特殊关键属性(与品牌表现评价反应时法选取的不一致的关键属性)的品牌表现对总体评价结果回归系数不显著。
