kurtosis

• kurtosis(alpha: number, beta: number): number

• Returns the excess kurtosis of an inverse gamma distribution.

  Notes

  • If alpha <= 0 or beta <= 0, the function returns NaN.

  Parameters

  • alpha: number

    shape parameter

  • beta: number

    rate parameter

  Returns number

  Example

  var v = kurtosis( 6.0, 1.0 );
  // returns 19.0

  Example

  var v = kurtosis( 5.0, 12.0 );
  // returns 42.0

  Example

  var v = kurtosis( 8.0, 2.0 );
  // returns ~8.7

  Example

  var v = kurtosis( 5.0, -0.1 );
  // returns NaN

  Example

  var v = kurtosis( 6.0, -0.1 );
  // returns NaN

  Example

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

  Example

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

  Example

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