Dear Statalisters,

I have developed a new Stata estimation command for quasi-maximum likelihood estimation of linear dynamic panel data models with a short time horizon, in particular the random-effects ML estimator by Bhargava and Sargan (1983) and the fixed-effects transformed ML estimator by Hsiao, Pesaran, and Tahmiscioglu (2002).

The program can be installed by typing

net from "http://www.kripfganz.de/stata/"

in Stata’s command window.

A help file that documents the command syntax and the available options can be accessed by typing

help xtdpdqml

Postestimation commands can be used as well, see

help xtdpdqml postestimation

A preliminary background note is available at www.kripfganz.de

Comments and suggestions are welcome.
