• Returns the excess kurtosis of an exponential distribution.

  Notes

  • If provided a negative value for λ, the function returns NaN.

  Parameters

  • lambda: number

    rate parameter

  Returns number

  excess kurtosis

  Example

  var v = kurtosis( 9.0 );
  // returns 6.0

  Example

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

  Example

  var v = kurtosis( -0.2 );
  // returns NaN

  Example

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