kurtosis

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

• Returns the excess kurtosis of a beta prime distribution.

  Notes

  • If alpha <= 0 or beta <= 4, the function returns NaN.

  Parameters

  • alpha: number

    first shape parameter

  • beta: number

    second shape parameter

  Returns number

  Example

  var v = kurtosis( 2.0, 6.0 );
  // returns ~26.143

  Example

  var v = kurtosis( 4.0, 12.0 );
  // returns ~5.764

  Example

  var v = kurtosis( 12.0, 6.0 );
  // returns ~19.49

  Example

  var v = kurtosis( 2.0, 4.0 );
  // returns NaN

  Example

  var v = kurtosis( 1.0, -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
