Signature

def trimtail(data, proportiontocut = 0.2, tail = left, inclusive = (True, True), axis = None)

Trims the data by masking values from one tail.

data : array_like: Data to trim.
proportiontocut : float, optional: Percentage of trimming. If n is the number of unmasked values before trimming, the number of values after trimming is (1 - proportiontocut) * n. Default is 0.2.
tail : {'left','right'}, optional: If 'left' the proportiontocut lowest values will be masked. If 'right' the proportiontocut highest values will be masked. Default is 'left'.
inclusive : {(bool, bool) tuple}, optional: Tuple indicating whether the number of data being masked on each side should be rounded (True) or truncated (False). Default is (True, True).
axis : int, optional: Axis along which to perform the trimming. If None, the input array is first flattened. Default is None.

trimtail : ndarray: Returned array of same shape as data with masked tail values.
