%description
Machine learning estimator specifically optimized for predictive modeling
of ordered non-numeric outcomes. 'ocf' provides forest-based estimation of
the conditional choice probabilities and the covariates’ marginal effects.
Under an "honesty" condition, the estimates are consistent and
asymptotically normal and standard errors can be obtained by leveraging
the weight-based representation of the random forest predictions. Please
reference the use as Di Francesco (2023) <doi:10.48550/arXiv.2309.08755>.
