- Regression analysis
- Multivariate statistics
- Structural equation modeling
- Missing data analysis
My primary quantitative research interests include model fit evaluation, growth curve modeling, structural equation modeling, multilevel (mixed) modeling and missing data analysis. I am also interested in the application of these methods in education, social, developmental and health related studies.
