scipy.stats.circstd¶
- scipy.stats.circstd(samples, high=6.283185307179586, low=0, axis=None)[source]¶
Compute the circular standard deviation for samples assumed to be in the range [low to high].
Parameters: samples : array_like
Input array.
low : float or int, optional
Low boundary for circular standard deviation range. Default is 0.
high : float or int, optional
High boundary for circular standard deviation range. Default is 2*pi.
axis : int, optional
Axis along which standard deviations are computed. The default is to compute the standard deviation of the flattened array.
Returns: circstd : float
Circular standard deviation.
Notes
This uses a definition of circular standard deviation that in the limit of small angles returns a number close to the ‘linear’ standard deviation.
