scipy.stats.tmean

scipy.stats.tmean(a, limits=None, inclusive=(True, True), axis=None)

Compute the trimmed mean.

This function finds the arithmetic mean of given values, ignoring values outside the given limits.

Parameters:

aarray_like

Array of values.

limitsNone 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 (default), then all values are used. Either of the limit values in the tuple can also be None representing a half-open interval.

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).

axisint or None, optional

Axis along which to compute test. Default is None.

Returns:

tmeanndarray

Trimmed mean.

trim_mean

Returns mean after trimming a proportion from both tails.

Examples

>>> import numpy as np
>>> from scipy import stats
>>> x = np.arange(20)
>>> stats.tmean(x)
9.5
>>> stats.tmean(x, (3,17))
10.0
