%description
The ordinal forest (OF) method allows ordinal regression with
high-dimensional and low-dimensional data. After having constructed an OF
prediction rule using a training dataset, it can be used to predict the
values of the ordinal target variable for new observations. Moreover, by
means of the (permutation-based) variable importance measure of OF, it is
also possible to rank the covariates with respect to their importance in
the prediction of the values of the ordinal target variable. OF is
presented in Hornung (2020). NOTE: Starting with package version 2.4, it
is also possible to obtain class probability predictions in addition to
the class point predictions. Moreover, the variable importance values can
also be based on the class probability predictions. Preliminary results
indicate that this might lead to a better discrimination between
influential and non-influential covariates. The main functions of the
package are: ordfor() (construction of OF) and predict.ordfor()
(prediction of the target variable values of new observations).
