Hello I created a MARS model from earth package.for one predictor EngDispl vs FE. These are the resulting coefficients:
summary(marsFit)$coefficients y (Intercept) 18.049001 h(EngDispl-4.3) -4.378082 h(4.3-EngDispl) 10.925240 h(EngDispl-2.3) 5.942387 h(EngDispl-3.5) -2.552332 I am at a loss at writing the equation linking the dependent and independent variables for such an output. What is h? Is it a function / operator? Thank you for your help Yousri fanous IBM Canada Software developer ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
