Emir Malikov (Economics) and his advisee, Shaymal Halder, a doctoral candidate in statistics at Auburn University, published an article, "Smoothed LSDV Estimation of Functional-Coefficient Panel Data Models with Two-Way Fixed Effects," in Economics Letters. The paper provides a semiparametric estimation procedure for varying-coefficient longitudinal models with fixed effects in both dimensions of the data: cross-section and time. Halder won a best student paper award for this work from the business & economics section of the American Statistical Association in 2020.
