Fonction trim1 - module scipy.stats

Signature de la fonction trim1

def trim1(a, proportiontocut, tail='right', axis=0) 

Description

trim1.__doc__

Slice 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).
    Slice off less if proportion results in a non-integer slice index
    (i.e. conservatively slices off `proportiontocut` ).

    Parameters
    ----------
    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`.

    Returns
    -------
    trim1 : ndarray
        Trimmed version of array `a`. The order of the trimmed content is
        undefined.

    Examples
    --------
    >>> from scipy import stats
    >>> a = np.arange(20)
    >>> b = stats.trim1(a, 0.5, 'left')
    >>> b
    array([10, 11, 12, 13, 14, 16, 15, 17, 18, 19])
