kurtosis - Function

Calculate the kurtosis of a set of numbers

Synopsis
kurtosis(dots, assumed_mean)

Description
This is a more convenient front end to moments. The kurtosis is the fourth moment.

You can tell it to assume a mean rather than calculating it if desired. NB: The assumed_mean argument must be explicitly indicated as in the example below ('assumed_mean=0', not just '0'); otherwise, the value specified will simply be included in the list of samples.

Arguments

dots	The numbers to perform statistics on
assumed_mean	If numeric, assume the mean is this value rather than calculating it; if used, parameter name must be explicitly specified
	Allowed:	numeric scalar
	Default:	[=]

Returns
the kurtosis

Example

      - include "statistics.g"
      - kurtosis(1:100)
      -1.23606
      - kurtosis(1:100,assumed_mean=50)   # instead of 50.5
      -1.23535
