Bivariate regression wikipedia
WebThe bivariate linear regression model is defined by: Y i = α + β × X i + ε i where ε i ∼ N ( 0, σ 2) This seems to refer to one response and one predictor (i.e. simple linear regression). So, in this case, does the term "bivariate" refer to … Web一般线性模型（general linear model, multivariate regression model）是一个统计学上常见的 线性模型 （ 英语 ： Linear model ） 。 这个模型在计量经济学的应用中十分重要。 不要与多元线性回归，广义线性模型或一般线性方法相混淆。. 其公式一般写为： = +, 其中Y是一个包含反应变量的矩阵。
