pht
estimates panels models using the Hausman–Taylor
estimator, Amemiya–MaCurdy estimator, or Breusch–Mizon–Schmidt estimator,
depending on the argument model
. The model is specified as a two–part
formula, the second part containing the exogenous variables.
An object of class c("pht", "plm", "panelmodel")
.
A "pht"
object contains the same elements as plm
, with a
further argument called varlist
which describes the typology of
the variables. It has summary
and print.summary
methods.
