kurtosis

• kurtosis(k: number, lambda: number): number

• Returns the excess kurtosis of an Erlang distribution.

  Notes

  • If not provided a positive integer for k, the function returns NaN.
  • If provided a non-positive value for lambda, the function returns NaN.

  Parameters

  • k: number

    shape parameter

  • lambda: number

    rate parameter

  Returns number

  excess kurtosis

  Example

  var v = kurtosis( 1, 1.0 );
  // returns 6.0

  Example

  var v = kurtosis( 4, 12.0 );
  // returns 1.5

  Example

  var v = kurtosis( 8, 2.0 );
  // returns 0.75

  Example

  var v = kurtosis( 1.5, 2.0 );
  // returns NaN

  Example

  var v = kurtosis( 1, -0.1 );
  // returns NaN

  Example

  var v = kurtosis( -0.1, 1.0 );
  // returns NaN

  Example

  var v = kurtosis( 2, NaN );
  // returns NaN

  Example

  var v = kurtosis( NaN, 2.0 );
  // returns NaN
