kurtosis

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

• Returns the excess kurtosis of a Weibull distribution.

  Notes

  • If k <= 0 or lambda <= 0, the function returns NaN.

  Parameters

  • k: number

    shape parameter

  • lambda: number

    scale parameter

  Returns number

  Example

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

  Example

  var v = kurtosis( 4.0, 12.0 );
  // returns ~-0.252

  Example

  var v = kurtosis( 8.0, 2.0 );
  // returns ~0.328

  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
