Superclasses: CompactRegressionEnsemble
Ensemble regression
RegressionEnsemble
combines a set of trained
weak learner models and data on which these learners were trained.
It can predict ensemble response for new data by aggregating predictions
from its weak learners.
Create a regression ensemble object using fitrensemble

Indices of categorical
predictors, stored as a vector of positive integers. 

A character vector describing how the ensemble combines learner predictions. 

Expanded predictor names, stored as a cell array of character vectors. If the model uses encoding for categorical variables, then 

A numeric array of fit information. The

Cell array of character vectors with names of the weak learners
in the ensemble. The name of each learner appears just once. For example,
if you have an ensemble of 100 trees,

A numeric vector of weights the ensemble assigns to its learners. The ensemble computes predicted response by aggregating weighted predictions from its learners.
