This research group focuses on the development and improvement of statistical methods for analyzing educational, psychological, and more generally social and behavioral sciences data, particularly longitudinal (measures repeated on the same individuals over time) data. The core agenda of this methodological research is to better understand nonlinear relationships among observed and latent variables using state-of-the-art latent variable methods, especially nonlinear mixed-effects models and its variants, and nonlinear structural equation models (e.g., piecewise growth models).
