Fonction trimboth - module scipy.stats

Signature de la fonction trimboth

def trimboth(a, proportiontocut, axis=0) 

Description

trimboth.__doc__

Slice off a proportion of items from both ends of an array.

    Slice off the passed proportion of items from both ends of the passed
    array (i.e., with `proportiontocut` = 0.1, slices leftmost 10% **and**
    rightmost 10% of scores). The trimmed values are the lowest and
    highest ones.
    Slice off less if proportion results in a non-integer slice index (i.e.
    conservatively slices off `proportiontocut`).

    Parameters
    ----------
    a : array_like
        Data to trim.
    proportiontocut : float
        Proportion (in range 0-1) of total data set to trim of each end.
    axis : int or None, optional
        Axis along which to trim data. Default is 0. If None, compute over
        the whole array `a`.

    Returns
    -------
    out : 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.trimboth(a, 0.1)
    >>> b.shape
    (16,)
