A Decorrelating and Debiasing Approach to Simultaneous Inference for High-Dimensional Confounded Models
Yinrui Sun, Li Ma, Yin Xia
Motivated by the simultaneous association analysis with the presence of latent confounders, this paper studies the large-scale hypothesis testing problem for the high-dimensional c…
A tree perspective on stick-breaking models in covariate-dependent mixtures
Akira Horiguchi, Cliburn Chan, Li Ma
Stick-breaking (SB) processes are often adopted in Bayesian mixture models for generating mixing weights. When covariates influence the sizes of clusters, SB mixtures are particula…
NAPA: Neighborhood-Assisted and Posterior-Adjusted Two-sample Inference
Li Ma, Yin Xia, Lexin Li
Two-sample multiple testing problems of sparse spatial data are frequently arising in a variety of scientific applications. In this article, we develop a novel neighborhood-assiste…
A tree-based model for addressing sparsity and taxa covariance in microbiome compositional count data
Zhuoqun Wang, Jialiang Mao, Li Ma
Microbiome compositional data are often high-dimensional, sparse, and exhibit pervasive cross-sample heterogeneity. Generative modeling is a popular approach to analyze such data,…
Unsupervised tree boosting for learning probability distributions
Naoki Awaya, Li Ma
We propose an unsupervised tree boosting algorithm for inferring the underlying sampling distribution of an i.i.d. sample based on fitting additive tree ensembles in a fashion anal…
Hidden Markov Pólya trees for high-dimensional distributions
Naoki Awaya, Li Ma
The Pólya tree (PT) process is a general-purpose Bayesian nonparametric model that has found wide application in a range of inference problems. It has a simple analytic form and th…
