rules

Introduction

rules is a parsnip extension package with model definitions for rule-based models, including:

• cubist models that have discrete rule sets that contain linear models with an ensemble method similar to boosting
• classification rules where a ruleset is derived from an initial tree fit
• rule-fit models that begin with rules extracted from a tree ensemble which are then added to a regularized linear or logistic regression.
