The main goal of the methods such as CART (Classification and Regression Trees),
is to model and predict one response variable explained by a set of dependent
variables. This methods can be particularly effective to model interactions
between explanatory variables. On the other hand, as a statistical model, a
neural network is based on linear and non-linear combinations of explanatory
variables that interact with other combinations to predict or explain an outcome
variable. Both CART and neural networks methods can provide good results to
explain or predict an outcome variable, particularly when the number of
interactions is important. Nevertheless, these techniques also tend to over-fit
the data and a validation of the models is required. ROC methods, including a
sensitivity/specificity analyses and/or external validations can be performed to
assess the consistency of these techniques. Applications cover a wide range of
problems, including species classification in biology, prediction of the
prognosis of a patient in biomedicine, etc.
