概念：多元线性回归分析也称复线性回归分析（multiplelinearregressionanalysis）,它研究一组自变量如何直接影响一个因变量。自变量（independentvariable）是指独立自由变量的变量，用向量X表示；因变量（dependentvariable)是指非独立的、受其它变量影响的变量，用向量Y表示；由于模型仅涉及一个因变量，所以多元线性回归分析也称...
6) multivariate linear regression analysis 多元线性回归分析 1. Methods A dataset composed of 190 diversified compounds,was studied by principal component analysis and multivariate linear regression analysis methods. 方法选择190个化合物作为数据集,采用主成分分析和多元线性回归分析相结合的方法,使用10个分子...
因变量(dependent variable)是指非独立的、受其它变量影响的变量,用向量Y表示;由于模型仅涉及一个因变量,所以多元线性回归分析也称单变量线性回归分析(univariate linear regression analysis) 多元回归分析数据格式 假定因变量Y与自变量 间存在如下关系: 式中, 是常数项, 称为偏回归系数(partial regression coefficient)...
A simple linear regression model: 方程右边仅有一个自变量/解释变量,方程左边仅有一个因变量/结局变量,所以简单线性回归既不属于Multivariable analysis,也不属于Multivariate analysis。 A multivariable or multiple linear regression model: 方程右边有多个自变量/解释变量,方程左边仅有一个因变量/结局变量,所以多元线性...

Assumption validation: The ANOVA tool used in the multivariate linear regression analysis to testify the validity and significance of the model is based on some assumptions, such as residuals having constant variance and being normally distributed. A graphical analysis of the residuals was carried out...
Multivariate regression analysis there are three main steps: First, using univariate and bivariate analyses to examine the various preparations into the regression analysis of the variables is consistent with the basic assumption of OLS linear regression analysis. - selected regression model, and evaluate...
