Metrics

Module with metrics of forecasting quality.

API details

Base:

Metric(metric_fn[, mode])

Base class for all the multi-segment metrics.

Enums:

MetricAggregationMode(value)

Enum for different metric aggregation modes.

Scalar metrics:

MAE([mode])	Mean absolute error metric with multi-segment computation support.
MAPE([mode])	Mean absolute percentage error metric with multi-segment computation support.
MSE([mode])	Mean squared error metric with multi-segment computation support.
MSLE([mode])	Mean squared logarithmic error metric with multi-segment computation support.
R2([mode])	Coefficient of determination metric with multi-segment computation support.
RMSE([mode])	Root mean squared error metric with multi-segment computation support.
SMAPE([mode])	Symmetric mean absolute percentage error metric with multi-segment computation support.
WAPE([mode])	Weighted average percentage Error metric with multi-segment computation support.
MaxDeviation([mode])	Max Deviation metric with multi-segment computation support (maximum deviation value of cumulative sums).
MedAE([mode])	Median absolute error metric with multi-segment computation support.
Sign([mode])	Sign error metric with multi-segment computation support.

Interval metrics:

Coverage([quantiles, mode])	Coverage metric for prediction intervals - precenteage of samples in the interval [lower quantile, upper quantile].
Width([quantiles, mode])	Mean width of prediction intervals.

Utilities:
