Model Selection for Exposure-Mediator Interaction
Ruiyang Li, Xi Zhu, Seonjoo Lee
In mediation analysis, the exposure often influences the mediating effect, i.e., there is an interaction between exposure and mediator on the dependent variable. When the mediator…
Longitudinal Canonical Correlation Analysis
Seonjoo Lee, Jongwoo Choi, Zhiqian Fang +1
This paper considers canonical correlation analysis for two longitudinal variables that are possibly sampled at different time resolutions with irregular grids. We modeled trajecto…
A Novel Causal Mediation Analysis Approach for Zero-Inflated Mediators
Meilin Jiang, Seonjoo Lee, James O'Malley +2
Mediation analyses play important roles in making causal inference in biomedical research to examine causal pathways that may be mediated by one or more intermediate variables (i.e…
Nonparametric Independent Component Analysis for the Sources with Mixed Spectra
Seonjoo Lee, Haipeng Shen, Young K. Truong
Independent component analysis (ICA) is a blind source separation method to recover source signals of interest from their mixtures. Most existing ICA procedures assume independent…
An M-Estimator for Reduced-Rank High-Dimensional Linear Dynamical System Identification
Shaojie Chen, Kai Liu, Yuguang Yang +5
High-dimensional time-series data are becoming increasingly abundant across a wide variety of domains, spanning economics, neuroscience, particle physics, and cosmology. Fitting st…
