scipy.stats.signaltonoise¶
- scipy.stats.signaltonoise(*args, **kwds)[source]¶
signaltonoise is deprecated! scipy.stats.signaltonoise is deprecated in scipy 0.16.0
The signal-to-noise ratio of the input data.
Returns the signal-to-noise ratio of a, here defined as the mean divided by the standard deviation.
Parameters: a : array_like
An array_like object containing the sample data.
- axis : int or None, optional
Axis along which to operate. Default is 0. If None, compute over the whole array a.
- ddof : int, optional
Degrees of freedom correction for standard deviation. Default is 0.
Returns: s2n : ndarray
The mean to standard deviation ratio(s) along axis, or 0 where the standard deviation is 0.
