%description
Provides a routine to partial out factors with many levels during the
optimization of the log-likelihood function of the corresponding
generalized linear model (glm). The package is based on the algorithm
described in Stammann (2018) <arXiv:1707.01815> and is restricted to glm's
that are based on maximum likelihood estimation and nonlinear. It also
offers an efficient algorithm to recover estimates of the fixed effects in
a post-estimation routine and includes robust and multi-way clustered
standard errors. Further the package provides analytical bias corrections
for binary choice models derived by Fernandez-Val and Weidner (2016)
<doi:10.1016/j.jeconom.2015.12.014> and Hinz, Stammann, and Wanner (2020)
<arXiv:2004.12655>.
