7.7 Other Potentially Useful Tools

• Multivariate adaptive regression splines (MARS) is a nonlinear modeling technique for a continuous response

• MARS has also been extended to classification outcomes, and this method is called flexible discriminant analysis (FDA).

• Cubist (Kuhn and Johnson 2013) is a rule-based regression model that builds an initial tree and decomposes it into set of rules that are pruned and perhaps eliminated.
