scipy.stats.trim1(a, proportiontocut, tail='right', axis=0)[source]

Slices off a proportion from ONE end of the passed array distribution.

If proportiontocut = 0.1, slices off ‘leftmost’ or ‘rightmost’ 10% of scores. The lowest or highest values are trimmed (depending on the tail). Slices off less if proportion results in a non-integer slice index (i.e., conservatively slices off proportiontocut ).


a : array_like

Input array

proportiontocut : float

Fraction to cut off of ‘left’ or ‘right’ of distribution

tail : {‘left’, ‘right’}, optional

Defaults to ‘right’.

axis : int or None, optional

Axis along which to trim data. Default is 0. If None, compute over the whole array a.


trim1 : ndarray

Trimmed version of array a. The order of the trimmed content is undefined.
