WebMay 5, 2024 · If you want to see the structure of the tree when allowing splits at less strict singificance levels (default is alpha = 0.05 ), you can use something like ctree (..., alpha = 0.8) etc. See ?ctree_control for further details. Whether or not the results of such a tree are useful for interpretation and/or prediction is a different question, though.

WebApr 29, 2013 · Tree methods such as CART (classification and regression trees) can be used as alternatives to logistic regression. It is a way that can be used to show the probability of being in any hierarchical group. The following is a compilation of many of the key R packages that cover trees and forests. WebA toolkit with infrastructure for representing, summarizing, and visualizing tree-structured regression and classification models. This unified infrastructure can be used for reading/coercing tree models from different sources ('rpart', 'RWeka', 'PMML') yielding objects that share functionality for print ()/plot ()/predict () methods.
