ocf implements the ordered correlation forest estimator, a machine learning estimator specifically designed for predictive modeling of ordered non-numeric outcomes.
The package delivers:
✔ Forest-based estimation of conditional choice probabilities.
✔ Marginal effects of covariates on the choice probabilities.
✔ Standard error estimation leveraging the weight-based structure of random forest predictions.
