# trimmed_mean

scipy.stats.mstats.trimmed_mean(a, limits=(0.1, 0.1), inclusive=(1, 1), relative=True, axis=None)

  Returns the trimmed mean of the data along the given axis.

  Parameters:
    a sequence

      Input array

    limits{None, tuple}, optional

      If relative is False, tuple (lower limit, upper limit) in absolute values. Values of the input array lower (greater) than the lower (upper) limit are masked.

      If relative is True, tuple (lower percentage, upper percentage) to cut on each side of the array, with respect to the number of unmasked data.

      Noting n the number of unmasked data before trimming, the (n*limits[0])th smallest data and the (n*limits[1])th largest data are masked, and the total number of unmasked data after trimming is n*(1.-sum(limits)) In each case, the value of one limit can be set to None to indicate an open interval.

      If limits is None, no trimming is performed

    inclusive{(bool, bool) tuple}, optional

      If relative is False, tuple indicating whether values exactly equal to the absolute limits are allowed. If relative is True, tuple indicating whether the number of data being masked on each side should be rounded (True) or truncated (False).

    relative bool, optional

      Whether to consider the limits as absolute values (False) or proportions to cut (True).

    axis int, optional

      Axis along which to trim.
