Binary regression tree
Webclassification or a continuous quantity for regression. A binary-split tree of depth dcan have at most 2d leaf nodes. In a multiway-split tree, each node may have more than two children. Thus, we use the depth of a tree d, as well as the number of leaf nodes l, which are user-specified pa-rameters, to describe such a tree. An example of a ... WebRegression Trees. Basic regression trees partition a data set into smaller groups and then fit a simple model (constant) for each subgroup. Unfortunately, a single tree model tends to be highly unstable and a poor predictor. ... The partitioning is achieved by successive binary partitions (aka recursive partitioning) based on the different ...

However, here are some general observations: Logistic regression is a linear model that tries to fit a decision boundary to the data that separates the two classes. Decision trees, on the other hand, can model complex nonlinear decision boundaries.
