def tvar(a, limits=None, inclusive=(True, True), axis=0, ddof=1) 

Description

help(scipy.stats.mstats.tvar)

Compute the trimmed variance

This function computes the sample variance of an array of values,
while ignoring values which are outside of 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).
axis : int or None, optional
    Axis along which to operate. If None, compute over the
    whole array. Default is zero.
ddof : int, optional
    Delta degrees of freedom. Default is 1.

Returns
-------
tvar : float
    Trimmed variance.
