This function allows to use a custom thresholding method to maximize the Matthews Correlation Coefficient.
metrics.mcc.max(preds, labels, threshold = FALSE)
| preds | Type: numeric. The predictions. | 
|---|---|
| labels | Type: numeric. The labels (0, 1). | 
| threshold | Type: logical. Whether to return the threshold. Defaults to  | 
A one or two element vector containing the maximum Matthews Correlation Coefficient for binary data, and the threshold used if requested. Returns -1 in case of errors.
