定义 线性回归(Linear regression)是一种以线性模型假设来拟合自变量与因变量之间关系的方法。通常来说,当自变量只有一个的情况被称为一元线性回归,自变量大于一个的情况被称为多元线性回归。 一元线性回归如下图所示,线性模型由图中直线表示。 基本原理 函数假设:线性函数 损失函数:平方损失函数 学习方法: 最小二乘...
【2.1.3】散点图线性拟合(Scatter plot with linear regression line of best fit,pearson) 如果你想了解两个变量如何相互改变,那么line of best fit就是趋势。 案例一: from scipy import stats import matplotlib.pyplot as plt x = [1,2,3,4] y = [3,5,7,10] # 10, not 9, so the fit isn'...
