running_mean

plasmapy.analysis.time_series.running_moments.running_mean(signal, radius: int)

Calculate the running mean of a sequence.

Parameters:

• signal (1D array_like) – Signal to be averaged.

• radius (int) – The number of points on either side of each point for which the running mean is being calculated. The window size is 2 * radius + 1.

Returns:

Running mean of signal with length len(signal) - 2 * radius.

Return type:

1D array_like

Raises:

• ValueError – If len(signal) <= 2 * radius.

• TypeError – If radius is not of type int.

Examples

>>> from plasmapy.analysis.time_series.running_moments import running_mean
>>> running_mean([1, 2, 3, 4], 1)
array([2., 3.])
