一、基于原生Python实现多元线性回归(Multiple Linear Regression)算法 多元线性回归是一种用于建立多个自变量与因变量之间关系的统计学方法。在多元线性回归中,我们可以通过多个自变量来预测一个因变量的值。每个自变量对因变量的影响可以用回归系数来表示。 在实现多元线性回归算法时,通常使用最小二乘法来求解回归系数。最...
Multiple linear regression (MLR) is a method for estimating how several independent factors together influence a single outcome. It fits a straight-line equation to data points to reveal how each variable contributes when the others are held steady. ...
Compute the regression coefficients for a linear model with an interaction term. X = [ones(size(x1)) x1 x2 x1.*x2]; b = regress(y,X)% Removes NaN data b =4×160.7104 -0.0102 -0.1882 0.0000 Plot the data and the model.
Use the object functions ofLinearModelto predict responses and to modify, evaluate, and visualize the linear regression model. Unlikeregress, thefitlmfunction does not require a column of ones in the input data. A model created byfitlmalways includes an intercept term unless you specify not to ...
