Description
xtdpdgmm: Generalized method of moments estimation of linear dynamic panel data models
xtdpdgmm implements generalized method of moments estimators for linear dynamic panel models. Linear moment conditions in the spirit of Arellano and Bond (1991), Arellano and Bover (1995), Blundell and Bond (1998), and Hayakawa, Qi, and Breitung (2019) can be combined with the nonlinear moment conditions suggested by Ahn and Schmidt (1995) or Chudik and Pesaran (2022). One-step, two-step, iterated, and continuously-updating GMM estimators can be used. The Windmeijer (2005) finite-sample standard error correction and the doubly-corrected misspecification-robust standard errors of Hwang, Kang, and Lee (2022) are available. Possible model transformations include first differences, deviations from within-group means, and forward-orthogonal deviations. Available postestimation statistics include the Arellano and Bond (1991) and Jochmans (2020) tests for autocorrelation of the residuals, the Sargan-Hansen test for the validity of the overidentifying restrictions, a generalized Hausman test, and the Andrews and Lu (2001) model and moment selection criteria.
