| Parameter | Description |
|---|---|
| X | numeric matrix: rows are observations and columns are predictors. |
| Y | vector: class labels with one label for each row of X. |
| Name, Value | optional name-value arguments accepted by the corresponding fitting function. |
| Parameter | Description |
|---|---|
| mdl | classification model object returned by the fitting function. |
| label | predicted class labels for new observations. |
| score | class scores or posterior-like values when the model provides them. |
ClassificationNaiveBayes stores a naive Bayes classifier with class prior probabilities and predictor distribution information.
Create this object with fitcnb. Use predict to classify new observations.
