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%.

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﹪。

By qualitative and quantitative analysis between stock markets price and macroeconomic variables that is GDP, inflation, money supply, interest rate and exchange rate, we conclude that these variables provides a benign long-run equilibrium relation with stock price, however there is a deviation interaction between stock price and macroeconomic variables during 2000 and 2003.except that we also analysis the interrelation between deposit, investment, consumption and stock price emphatically, and farther conclude those promotable interaction.

通过经济周期和宏观经济变量：国内生产总值、通货膨胀、货币供应量、利率和汇率，与股票价格的定性理论分析和定量的线性相关、回归方程分析，得出了在1991年至2002年期间我国股市价格与宏观经济相互促进、2000年至2003年股市价格与宏观经济相背离的结论。除此之外，本文还分析了股市价格与储蓄、投资和消费的关系，进一步说明了股市与储蓄、投资和消费的相互促进关系。

Multiple linear regression is the simplest way to build the relationship between the several explanatory variables and response variable. However, MLR often causes the estimated regression coefficients unstable or even unaccessible when the number of explanatory variables is more than that of objects. Especially, the explanatory variables are highly intercorrelated which called multi-collinear data. Therefore, many methods have been developed to analyze multi-collinear data, such as variable selection methods, ridge regression, principal components regression and partial least squares regression.

当要同时建立多个解释变数与反应变数间的关系时，最简单的方式是以复回归来处理，但是当解释变数数目远多於样本数，或者变数之间具有高度相关性时，会使得回归系数的估计变得不稳定甚至无法求得，这样的资料又称为共线性资料，在面临这样的资料时可以利用变数选取的方式降低资料组的维度，或者以脊回归、主成分回归及净最小平方回归等方法来灭种共线性的干扰。

The purpose of the study was firstly to investigate the influences of social variables, i.e., the involvement of drug abuse, self-strength, self- esteem, the desire for control, irrational beliefs about drugs, drug-craving, on the intention to relapse. Secondly, it investigated the variables of demographic variables, i.e., sex, age, condition of marriage, education, occupation, relating to the intention of relapse, in order to build a model of illicit drugs relapse.
