多重线性

The book covers such topics as the problem of collinearity in multiple regression, dealing with outlying and influential data, non-normality of errors, non-constant error variance and the problems and opportunities presented by discrete data.

本书内容涵盖了在多重共线性回归问题等议题，与外围和有影响的数据，非错误，非正常常数误差方差的问题和离散数据处理带来的机遇。

A complete novel assumption is presented. Then, we prove the existence of two nontrivial solutions for a class of second order superlinear difference systems with the help of Minimax principle and Linking theorem in critical point theory,.6. Two applications in physics are given. Firstly, a coupled differential system coming from second harmonic waves is discussed.

利用Ricceri建立的三临界点定理，证明了一类含参数二阶差分方程在某些新的条件下至少存在三个解；随后，利用临界点理论中的极小极大原理和环绕定理，讨论了一类二阶超线性差分方程组多重解的存在性。

Severe multicollinearity means the variance of the estimated parameter will be very large.

严重的多重共线性意味着被估计参数的方差将非常大。

One hand, in the application of multilinear regression , the harm of multicollinearity is very serious, but the existence of multicollinearity is widespread.

一方面，在多元线性回归的应用中，变量之间多重相关性的危害十分严重，但其存在却又十分普遍。

When Rj2 is very close to 1, xj is highly correlated with other regressors, this is called multicollinearity.

当Rj2非常接近1时， xj与其它解释变量高度相关，被称为多重共线性。

Therefore,the thesis carries on the test by selecting the data of china stock exchange between 2004 and 2005 and revises the model accordingly to overcome multicollinearity and heteroscedasticity.

为此，选取2004-2005年的国内股票市场数据进行了这一检验，并对模型进行了修正，以克服多重共线性和异方差性。

This paper proposes the logistic default probability measure model which is based on the factor analysis , in the light of the problem of missing original data 、multicollinearity and without time consideration in the general Logistic probability of default model.

本文针对一般Logistic 违约率模型中原始数据信息的丢失、多重共线性以及没有考虑时间因素等问题，提出了基于因子分析的logistic违约概率测算模型。

Stment to developed country and the Chinese direct investment to developing country. On this basis, we get four regression models. Considering there are more variables in the equations, It will product multicollinearity, so we utilized a new method which is ridge regression.

在这个基础上，我们提出了四个回归模型，由于考虑到方程中的变量较多，产生了多重共线性的现象，在回归过程中我们利用的是岭回归的方法。
