Statistics & Data Science

About Us

HETU Lab develops scalable statistical methods for high-dimensional and dependent data. We connect statistical theory, computation, and domain knowledge to study questions across disciplines.

Led by Yizhou (Jake) Cai in the Department of Mathematics at Texas State University, our work spans inference, latent-variable models, structural changes, and interdisciplinary data science.

Identifying structural changes and studying causal questions in multivariate and evolving data.

Interdisciplinary Research

Public Health & Mental Health

Health-related information, social media, and changes in mental-health trajectories.

Finance & Insurance

Insurance claims, spatial risk, and dependence modeling.

Education

Collaborative statistical research on questions in education.
