The focus of this post is to explain the algorithm in a A new and flexible regression model, Multivariate Adaptive Regression Splines ( MARS), is introduced and applied to simulate soil temperature at three depths. This paper explores the use of another promising procedure known as multivariate adaptive regression spline (MARS) [3] to model nonlinear and multidimensional algorithm to improve the accuracy of the Multivariate Adaptive Regression Splines (MARS) modelling to effectively predict NOX emissions of vehicles in 2.
