| Parameter | Description |
|---|---|
| X | numeric matrix: rows are observations and columns are predictors. |
| y | numeric vector: response values with one value for each row of X. |
| Name, Value | optional name-value arguments accepted by the corresponding fitting function. |
| Parameter | Description |
|---|---|
| mdl | regression model object returned by the fitting function. |
| yfit | predicted response values for new observations. |
RegressionTree stores a regression tree built from predictor data and a numeric response.
Create this object with fitrtree. Use predict to estimate responses for new observations.
X = [1 1; 2 1; 3 2; 4 3; 5 3; 6 4];
y = 1 + 2 * X(:,1) - X(:,2);
mdl = fitrtree(X, y);
