kurtosis

• kurtosis(sigma: number): number

• Returns the excess kurtosis of a Rayleigh distribution.

  Notes

  • If provided σ < 0, the function returns NaN.

  Parameters

  • sigma: number

    scale parameter

  Returns number

  excess kurtosis

  Example

  var v = kurtosis( 9.0 );
  // returns ~0.245

  Example

  var v = kurtosis( 5.0 );
  // returns ~0.245

  Example

  var v = kurtosis( 3.0 );
  // returns ~0.245

  Example

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

  Example

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