the linear regression model is called linear becausef(x;β)is linear of the parameters{βi} 3. Parameter estimation 3.1. General procedure: (1) select a measure of fitness (2) optimize the measure with respect to the model parameters for a data set ...
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。 ...
