running_statistics

running_statistics(x, state=None)

Streaming summary statistics.

Accumulates count, extremes, and the first four moments over one or more chunks of data, mirroring the C# RunningStatistics class. The accumulator state travels in the return value, so a chunked run holds no C++ state.

Parameters

Name	Type	Description	Default
x	array_like	The next chunk of data.	required
state	RunningStatistics	A :class:RunningStatistics from a previous call, or None (the default) to start a fresh accumulator.	None

Returns

Name	Type	Description
	RunningStatistics

Examples

>>> from corehydropy import running_statistics
>>> s = running_statistics([1, 2, 3])
>>> s = running_statistics([4, 5, 6], state=s)
>>> s.n
6.0
>>> s.mean
3.5
