# scipy.stats.mstats.kurtosis

scipy.stats.mstats.kurtosis(a, axis=0, fisher=True, bias=True)

  Computes the kurtosis (Fisher or Pearson) of a dataset.

  Kurtosis is the fourth central moment divided by the square of the variance. If Fisher’s definition is used, then 3.0 is subtracted from the result to give 0.0 for a normal distribution.

  If bias is False then the kurtosis is calculated using k statistics to eliminate bias coming from biased moment estimators

  Use `kurtosistest` to see if result is close enough to normal.

  Parameters
    a array

      data for which the kurtosis is calculated

    axis int or None, optional

      Axis along which the kurtosis is calculated. Default is 0. If None, compute over the whole array a.

    fisher bool, optional

      If True, Fisher’s definition is used (normal ==> 0.0). If False, Pearson’s definition is used (normal ==> 3.0).

    bias bool, optional

      If False, then the calculations are corrected for statistical bias.

  Returns
    kurtosis array

      The kurtosis of values along an axis. If all values are equal, return -3 for Fisher’s definition and 0 for Pearson’s definition.
