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...
b = regress(y,X) returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X. To compute coefficient estimates for a model with a constant term (intercept), include a column of ones in the matrix X. example [b...
Multiple regression analysis (MR) is a highly flexible system for examining the relationship of a collection of independent variables (or predictors) to a single dependent variable (or criterion). The independent variables may be quantitative (e.g., personality traits, family income) or categorical...
