贝叶斯分位数加性回归树

Bayesian quantile additive regression trees

Bereket P. Kindo, Hao Wang, Timothy Hanson, Edsel A. Peña

摘要:

在给定一组预测变量的条件均值估计中,回归树的嵌入已经成为流行的统计工具。然而,尽管线性分位数回归模型越来越受欢迎,但分位数回归树及其集成尚未获得太多关注。这项工作提出了一个贝叶斯分位数加性回归树模型,显示出非常好的预测性能,说明使用模拟研究和实际数据的应用。还考虑了进一步扩展以解决二进制分类问题。

英文摘要:

Ensemble of regression trees have become popular statistical tools for the estimation of conditional mean given a set of predictors. However, quantile regression trees and their ensembles have not yet garnered much attention despite the increasing popularity of the linear quantile regression model. This work proposes a Bayesian quantile additive regression trees model that shows very good predictive performance illustrated using simulation studies and real data applications. Further extension to tackle binary classification problems is also considered.
