scipy.stats.tstd

scipy.stats.tstd(a, limits=None, inclusive=(1, 1))

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

array of values

limits : None or (lower limit, upper limit), optional

Values in the input array less than the lower limit or greater than the upper limit will be ignored. When limits is None, then all values are used. Either of the limit values in the tuple can also be None representing a half-open interval. The default value is None.

inclusive : (bool, bool), optional

A tuple consisting of the (lower flag, upper flag). These flags determine whether values exactly equal to the lower or upper limits are included. The default value is (True, True).

Returns :

tstd : float
