MaxDeviation

class MaxDeviation(mode: str = MetricAggregationMode.per_segment, **kwargs)

Bases: etna.metrics.base.Metric

Max Deviation metric with multi-segment computation support (maximum deviation value of cumulative sums).

\[MaxDeviation(y\_true, y\_pred) = \max_{j} | y_j |, where \, y_j = \sum_{i=1}^{j}{y\_pred_i - y\_true_i}\]

Notes

You can read more about logic of multi-segment metrics in Metric docs.

Init metric.

Parameters
