inner_implements_multilevel#

inner_implements_multilevel()[source]#

Extension tag: whether the metric implements multilevel evaluation.

String name: "inner_implements_multilevel"
Extension developer tag
Values: boolean, True / False
Example: True
Default: False

Metrics broadcast by default over time series hierarchy indices. If the tag is False, the inner _evaluate and _evaluate_by_index methods are written for individual time series only, and the boilerplate machinery is expected to handle hierarchy indices.

By setting this tag to False, developers can force the hierarchical time series to be passed to _evaluate and _evaluate_by_index, to treat the hierarchy index in deviation from the default.
