Here we propose a novel regression algorithm, automatic piecewise linear regression (APLR), that combines the predictiveness of a boosting algorithm with the interpretability of a MARS model. In addition, as a boosting algorithm, it automatically handles variable selection, and, as a MARS-based ...
教程地址:https://www.statology.org/piecewise-regression-in-r/ 分段回归(Piecewise Regression),也称为分段线性回归或阶梯回归,是一种用于描述变量之间关系在不同区间内有不同模式的统计模型。在简单线性回归中,我们假设因变量和自变量之间有一个恒定的关系,用一条直线来描述。然而,在许多情况下,这种关系可能在不...
