Hybrid Density- and Partition-based Clustering Algorithm for Data with Mixed-type Variables

no code implementations6 May 2019 Shu Wang, Jonathan G. Yabes, Chung-Chou H. Chang

However, algorithms that can cluster data with mixed variable types (continuous and categorical) remain limited, despite the abundance of data with mixed types particularly in the medical field.

A Bayesian Finite Mixture Model with Variable Selection for Data with Mixed-type Variables

no code implementations9 May 2019 Shu Wang, Jonathan G. Yabes, Chung-Chou H. Chang

To address these challenges, we propose a Bayesian finite mixture model to simultaneously conduct variable selection, account for biomarker LOD and obtain clustering results.

A Tree-based Model Averaging Approach for Personalized Treatment Effect Estimation from Heterogeneous Data Sources

1 code implementation10 Mar 2021 Xiaoqing Tan, Chung-Chou H. Chang, Ling Zhou, Lu Tang

We propose a tree-based model averaging approach to improve the estimation accuracy of conditional average treatment effects (CATE) at a target site by leveraging models derived from other potentially heterogeneous sites, without them sharing subject-level data.
