Simple Linear Regression 是用来描述一个自变量和一个因变量之间线性关系的回归模型 y=f(x) 从数据的角度上来看,y和x均为一列数字,即y和x的数据形状均为nX1 ,n为样本数目 Multiple Linear Regression Multiple Linear Regression 是用来描述多个(大于一个)自变量和一个因变量之间线性关系的回归
1. Simple Linear Regression Simple linear regression is useful for predicting and understanding correlations between one independent variable and one dependent variable. Y = m*x + c 2. Multiple Linear Regression Multiple regression is similar to linear regression, but it includes more than one indep...

Learn how to run multiple and simple linear regression in R, how to interpret the results and how to verify the conditions of application
simple linear regressionOne of the simplest and yet a commonly occurring data analytic problem is exploring the relationship between two numerical variables. In many applications, one of the variables may be regarded as a response variable and the other as a predictor variable and the goal is to...
