Modeling Nonlinear Ability Trajectories and Learner Heterogeneity in Online Learning: A Bayesian Nonparametric Dynamic IRT Framework
Zhihua Ma, Alice Xu, Icy Zhang +1
Online learning has amplified the need to understand how student engagement patterns influence learning outcomes, particularly given the flexibility of technology-mediated environm…
Non-segmental Bayesian Detection of Multiple Change-points
Chong Zhong, Zhihua Ma, Xu Zhang +1
We propose an original and general NOn-SEgmental (NOSE) approach for the detection of multiple change-points. NOSE identifies change-points by the non-negligibility of posterior es…
Dependent Dirichlet Processes for Analysis of a Generalized Shared Frailty Model
Chong Zhong, Zhihua Ma, Junshan Shen +1
Bayesian paradigm takes advantage of well fitting complicated survival models and feasible computing in survival analysis owing to the superiority in tackling the complex censoring…
Bayesian Hierarchical Spatial Regression Models for Spatial Data in the Presence of Missing Covariates with Applications
Zhihua Ma, Guanyu Hu, Ming-Hui Chen
In many applications, survey data are collected from different survey centers in different regions. It happens that in some circumstances, response variables are completely observe…
Geographically Weighted Regression Analysis for Spatial Economics Data: a Bayesian Recourse
Zhihua Ma, Yishu Xue, Guanyu Hu
The geographically weighted regression (GWR) is a well-known statistical approach to explore spatial non-stationarity of the regression relationship in spatial data analysis. In th…
A Nonparametric Bayesian Item Response Modeling Approach for Clustering Items and Individuals Simultaneously
Guanyu Hu, Zhihua Ma, Insu Paek
Item response theory (IRT) is a popular modeling paradigm for measuring subject latent traits and item properties according to discrete responses in tests or questionnaires. There…
Bayesian Clustered Coefficients Regression with Auxiliary Covariates Assistant Random Effects
Guanyu Hu, Yishu Xue, Zhihua Ma
In regional economics research, a problem of interest is to detect similarities between regions, and estimate their shared coefficients in economics models. In this article, we pro…
Heterogeneous Regression Models for Clusters of Spatial Dependent Data
Zhihua Ma, Yishu Xue, Guanyu Hu
In economic development, there are often regions that share similar economic characteristics, and economic models on such regions tend to have similar covariate effects. In this pa…
