kurtosis

• kurtosis(a: number, b: number): number

• Returns the excess kurtosis of a Kumaraswamy's double bounded distribution.

  Notes

  • If a <= 0 or b <= 0, the function returns NaN.

  Parameters

  • a: number

    first shape parameter

  • b: number

    second shape parameter

  Returns number

  excess kurtosis

  Example

  var v = kurtosis( 0.5, 1.0 );
  // returns ~2.143

  Example

  var v = kurtosis( 4.0, 12.0 );
  // returns ~2.704

  Example

  var v = kurtosis( 12.0, 2.0 );
  // returns ~4.817

  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
