Bayesian Classification and Regression Tree Analysis (CART)

The goal of genome-wide prediction GWP is to predict phenotypes based on marker genotypes, often obtained through single nucleotide polymorphism SNP chips. The major problem with GWP is high-dimensional data from many thousands of SNPs scored on several thousands of individuals. A large number of methods have been developed for GWP, which are mostly parametric methods that assume statistical linearity and only additive genetic effects. The Bayesian additive regression trees BART method was recently proposed and is based on the sum of nonparametric regression trees with the priors being used to regularize the parameters. Each regression tree is based on a recursive binary partitioning of the predictor space that approximates an unknown function, which will automatically model nonlinearities within SNPs dominance and interactions between SNPs epistasis.

Classification and Regression Trees

It can be considered a Bayesian version of machine learning tree ensemble methods where the individual trees are the base learners. However for datasets where the number of variables p is large the algorithm can become inefficient and computationally expensive. Another method which is popular for high dimensional data is random forests, a machine learning algorithm which grows trees using a greedy search for the best split points.

Decision tree learning is one of the predictive modelling approaches used in statistics , data mining and machine learning. It uses a decision tree as a predictive model to go from observations about an item represented in the branches to conclusions about the item's target value represented in the leaves. Tree models where the target variable can take a discrete set of values are called classification trees ; in these tree structures, leaves represent class labels and branches represent conjunctions of features that lead to those class labels.
