Simple linear regression analysis is a statistical tool for quantifying the relationship between one independent variable (hence “simple”) and one dependent variable based on past experience (observations). Based on entering a reasonable number of observations of the independent and dependent variables,...

2.Simple linear regression examples(简单线性回归案例)
Simple linear regression is used to model the relationship between two continuous variables. Often, the objective is to predict the value of an output variable based on the value of an input variable.
