Description
xtdpdqml: Quasi-maximum likelihood estimation of linear dynamic short-T panel data models
xtdpdqml implements the unconditional quasi-maximum likelihood estimators of Bhargava and Sargan (1983) for linear dynamic panel models with random effects and Hsiao, Pesaran, and Tahmiscioglu (2002) for linear dynamic panel models with fixed effects when the number of cross sections is large and the time dimension is fixed. In the fixed-effects case, the estimator of Hsiao, Pesaran, and Tahmiscioglu (2002) maximizes the transformed likelihood function after a first-difference transformation of the model. Robust standard errors are available and unbalanced panel data sets are supported.
