1. R平方 R方(R squared)又称为判定系数(coefficient of determination),是一种衡量回归模型表现的指标,代表从自变量可以解释因变量的比例。 残差平方和 可以解释的部分听起来有点抽象,或许从不能解释的部分来思考更容易理解,对于一个模型来说,什么叫做不能解释的部分?就是残差(residual)。我们耳熟能详的公式: 真...

The linear regression analysis is performed with these two R commands: XML > model<-lm(data$Rate~ (data$Color+data$Length+data$Width)) >summary(model) You can interpret the first command as, “Store into an object named model the result of the lm (linear model) f...
