biasCorr {alpaca} | R Documentation |
biasCorr
is a post-estimation routine that can be used to substantially reduce the
incidental parameter bias problem (Neyman and Scott (1948)) present in non-linear fixed effects
models (see Fernandez-Val and Weidner (2018) for an overview). The command applies the analytical
bias-correction derived by Fernandez-Val and Weinder (2016) to obtain bias-corrected estimates of
the structural parameters and is currently restricted to logit and probit models.

unsigned integer indicating a bandwidth for the estimation of spectral densities proposed by Hahn and Kuersteiner (2011). Default is zero, which should be used if all regressors are assumed to be strictly exogenous. In the presence of weakly exogenous or predetermined regressors, Fernandez-Val and Weidner (2016, 2018) suggest to choose a bandwidth not higher than four. |
The function biasCorr
returns a named list of classes "biasCorr"
and
