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.
简单线性回归(Simple Linear Regression)(附代码) 简单线性回归是最基础的一种回归模型,自变量只有一个,函数曲线为直线,因变量为连续型,自变量可以是连续的或者是离散的。函数表示如下: 其中y 是因变量, x是自变量, β0 和β1 属于起始值和系数,ε 为偏移量,为了使得到的函数模型更加准确,最后会加上偏移量。 ...
