%description
An implementation of the Ordered Forest estimator as developed in Lechner
& Okasa (2019) <arXiv:1907.02436>. The Ordered Forest flexibly estimates
the conditional probabilities of models with ordered categorical outcomes
(so-called ordered choice models). Additionally to common machine learning
algorithms the 'orf' package provides functions for estimating marginal
effects as well as statistical inference thereof and thus provides similar
output as in standard econometric models for ordered choice. The core
forest algorithm relies on the fast C++ forest implementation from the
'ranger' package (Wright & Ziegler, 2017) <arXiv:1508.04409>.
