While parametric regression models like linear and logistic regression are still the mainstay of statistical modeling, they are not the only, nor always the best, approach to predicting outcome 
variables.
Classification and Regression Trees (CART) are a nonparametric approach to using values of predictors to find good predictions of values of a response variable.
On each step, the values of a predictor variable are optimally split such that they predict the values of the response variable. The set of splits across multiple predictors leads to a tree.
CART models work for either categorical or numerical response variables and predictor variables, and they are especially good at revealing complex interactions among predictors. So they work well as either an exploratory technique before or a predictive model instead of logistic or linear regression.
In this webinar, we’ll explore CART modelling and discuss what it is, which options work when, and how to interpret the output.
