stdev

• stdev(mu: number, b: number): number

• Returns the standard deviation for a Laplace distribution with location mu and scale b.

  Notes

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

  Parameters

  • mu: number

    location parameter

  • b: number

    scale parameter

  Returns number

  standard deviation

  Example

  var y = stdev( 0.0, 1.0 );
  // returns ~1.414

  Example

  var y = stdev( 5.0, 2.0 );
  // returns ~2.828

  Example

  var y = stdev( NaN, 1.0 );
  // returns NaN

  Example

  var y = stdev( 0.0, NaN );
  // returns NaN

  Example

  var y = stdev( 0.0, 0.0 );
  // returns NaN
