autocart                Create an autocart model
autocartControl         Create the object used for the controlling of
                        the splits in the autocart model
autoforest              Create a forest of autocart trees..
autotune                Find the best alpha, beta, and bandwidth values
                        with k-fold cross-validation
predictAutocart         Given an autocart model object, predict for new
                        data passed in
predictAutoforest       Make a prediction using an autoforest model
                        returned from the 'autoforest' function.
rmae                    Relative mean absolute error
spatialNodes            Using an autocart model, use the terminal nodes
                        to form a spatial process that uses inverse
                        distance weighting to interpolate. The
                        prediction for the new data that is passed in
                        is formed by making a prediction to assign it
                        to a group. Next, the residual for the new
                        prediction is formed by inverse distance
                        weighting the residual for the other points
                        that are a part of that geometry.
