Compute the trimmed sample standard deviation
This function finds the sample standard deviation of given values, ignoring values outside the given limits.
Parameters: | a : array_like
limits : None or (lower limit, upper limit), optional
inclusive : (bool, bool), optional
|
---|---|
Returns: | tstd : float |
Notes
tstd computes the unbiased sample standard deviation, i.e. it uses a correction factor n / (n - 1).
