2. 多元线性回归 多元线性回归(multiple linear regression)为线性回归中自变量在两个以上的情形,此时回归模型的选 择具有很大的灵活性。对于全部自变量,可以将它们全部放在模型中,也可以只选择其中一部分进行回归 分析,而选择变量的途径也有多种,一般常用的有前进法(forward) 、后退法(backward)以及逐步回归 法(stepwi...

Linear Regression Simple linear regression is used when one wants to test how well a variable predicts another variable. Multiple linearregression allows one to test how well multiple variables predict a variable of interest. When using multiple linear regression, we additionally assume the predictor ...
