# hdquantiles

scipy.stats.mstats.hdquantiles(data, prob=(0.25, 0.5, 0.75), axis=None, var=False)

  Computes quantile estimates with the Harrell-Davis method.

  The quantile estimates are calculated as a weighted linear combination of order statistics.

  Parameters:
    dataarray_like

      Data array.

    probsequence, optional

      Sequence of probabilities at which to compute the quantiles.

    axisint or None, optional

      Axis along which to compute the quantiles. If None, use a flattened array.

    varbool, optional

      Whether to return the variance of the estimate.

  Returns:
    hdquantilesMaskedArray

      A (p,) array of quantiles (if var is False), or a (2,p) array of quantiles and variances (if var is True), where `p` is the number of quantiles.
