Abstract: xtpqml provides a wrapper for "xtpoisson, fe" that computes robust standard errors, as described by J. Wooldridge in the Journal of Econometrics (1999, 77-97). This specification produces consistent estimates under relatively weak assumptions: only the conditional mean need be correctly specified, but the standard errors usually need adjustment to account for over (under) dispersion.

Language: Stata
Requires: Stata version 8
Keywords: Poisson regression; fixed effects; panel data; robust; dispersion (search for similar items in EconPapers)
