prediction_ratio

prediction_ratio(true_change_points: Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], pred_change_points: Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str]) → float

Prediction ratio is the ratio of number of predicted to true change points.

Parameters:

true_change_points: array_like

Integer indexes (positions) of true change points

pred_change_points: array_like

Integer indexes (positions) of predicted change points

Returns:

prediction_ratio
