MultiWelford¶

class passengersim.tracers.welford.MultiWelford(keys: list[str], aux: dict[str, Any] | set[str] = None)[source]¶

Bases: object

Initialize a MultiWelford object.

Parameters:

keys : list[str]¶

The keys of the input dict.

aux : dict[str, Any], optional¶

Auxiliary data to store with the statistics. This can be labels or other constant data, which is not tracked by the online statistics algorithm, but is useful for plotting or other analysis and is stored and returned with the statistics.

Methods

__init__(keys[, aux])	Initialize a MultiWelford object.
update(x)
