Logistic regression analysis showed that the OR value of non-HDL-C is 1.032 (95% CI 1.011-1.049) for the positive angiograph group and the negative group, 1.007 (95% CI 1.002-1.012) between one vessel lesion and multi-vessel lesions, better than LDL-C. 3. The multivariant stepwise regression analysis of the vessel number, severity and lipids of coronary artery lesions showed that non-HDL-C was the best indicator in the male patients group who were under the age of 55 years.

Logistic回归结果显示在冠造阳性和阴性、1支病变与多支病变的比较中non-HDL-C的OR值分别是OR=1.032(95% CI1.011-1.049)和OR=1.007(95%CI1.002-1.012)，略强于LDL-C；③冠状动脉病变支数、程度与脂质成份的逐步回归显示，non-HDL-C是年龄小于55岁的男性患者组中最主要的相关因素。

That attical is to appty the regression analysis and the colleet analy- sis in the mathematics statistics method to make the first definite mea- sure analysis for recationship of physical geography factor and divis on of geographical type.

In full-time model of the salary regression, this text with career planning regression analysis result be adjusted according to the multinominal logit model . The text find height taller female university student, possess taller full-time of the salary level, weight heavier female university student the full-time salary level then will be notable to reduce, when the female university student has self-confidence will be notable to promote full-time salary level. In addition match the of the shape's limit influence toward whole self-confidence and can also beg to be from a material for early "indirect" influence.

在全职薪资回归模型中，本文以生涯规划回归分析结果作为调整依据，即全职薪资的样本选择模型，本文发现身高较高的女大学生，其享有较高的全职薪资水准；体重较重的女大学生则全职薪资水准会显著降低；当女大学生有自信时，会显著提升全职薪资水准，此外搭配身材对於整体自信的边际影响，亦能求出身材对於初期全职薪资的「间接」影响。

Returning to the classical Marxism-Leninism literary theory, the system of literary social value has witnessed adjustment from top to bottom in the new period, resulting in so-called "aesthetic" ideology,"active" theory of reflection and "humanistic" care. At the same time, it has seen total improvement: approval of aesthetic freedom, return and confirmation of subjectness, appreciation and celebration of humanity and humanism, and the opening and evolution of Marxism-Leninism literary theory.

回归经典马列文论，新时期文学社会价值论体系进行了自上而下的调整：&审美的&意识形态，&能动的&反映论和&人性、人民性&关怀；同时在多种社会合力作用下，开始了自下而上的改新：&审美自由、主体性的回归与肯定&，&'人性'、'人文精神'的认同与高扬&，&'马列文论'由封闭走向开放、由独断走向融和&。

Accurate load forecasting is helpful to planning generators starting and stopping in the interior of the electrical networks economically and reasonably, preserving the security and stability of power system, reducing the unnecessary circumvolving repertory capacity, making planning to overhaul the units in reason, ensuring the normal production and life of the society, effectively reducing the cost of generating ...

本文在探讨了电力系统负荷的组成、特点，并分析比较了常用的预测方法优缺点的基础之上，采用了灰色预测法与线性回归法相结合的方法建立了中长期负荷预测模型，把负荷预测工作分为两部分：即用灰色预测法进行相关因素的预测和用线性回归法进行负荷预测。

The outstanding characteristic of PLS is that it can make the multiple linear regression analysis, the principal components analysis and the canonical correlation analysis combined. In the same arithmetic, it can implement modeling, predigesting the data structure and analyzing of the correlation between two gropes of variables at the same time. It brings huge advantage to the multiple linear regression analysis.
