Abstract. qregpd can be used to fit the quantile regression for panel data (QRPD) estimator developed in Powell (2015). The estimator addresses a fundamental problem posed by alternative fixed-effect quantile estimators: inclusion of individual fixed effects alters the interpretation of the estimated coefficient on the treatment variable.To the best of my knowledge and research in the statalist forums, I came to notice that there are several options to regress. Option 1: xtnbreg, fe such as: Code: xtset state year xtnbreg new_firms bank_concentration vc_firms GDP_growth i.year. Option 2: nbreg with dummy vectors.
