Kurtosis

Kurtosis is a statistic that is used to measure the distribution tails of a set of data. The kurtosis of an analysis domain is calculated as follows:

summation is over all samples i in the region.

n	is the number of samples included in the summation.
Ei	is the linear Sv of sample i (m2/m3) -  set to 0 for any sample where Ei < mSv or Ei > MSv,
En	is the observed Mean Energy of the region in linear units (m2/m3) = 10Sv/10
mSv	is the minimum integration threshold (dB re 1 m-1) at time of processing.
MSv	is the maximum integration threshold (dB re 1 m-1) at time of processing.
ESD	Standard_deviation (Standard Deviation of the Energy)

All symbols are as defined in the nomenclature developed for SHAPES algorithms.
