stdev

• stdev(a: number, b: number): number

• Returns the standard deviation of a discrete uniform distribution.

  Notes

  • If a or b is not an integer value, the function returns NaN.
  • If provided a >= b, the function returns NaN.

  Parameters

  • a: number

    minimum support

  • b: number

    maximum support

  Returns number

  standard deviation

  Example

  var v = stdev( 0, 1 );
  // returns ~0.5

  Example

  var v = stdev( 4, 12 );
  // returns ~2.582

  Example

  var v = stdev( -4, 4 );
  // returns ~2.582

  Example

  var v = stdev( 1, -0.1 );
  // returns NaN

  Example

  var v = stdev( 0.5, 1 );
  // returns NaN

  Example

  var v = stdev( 2, NaN );
  // returns NaN

  Example

  var v = stdev( NaN, 2 );
  // returns NaN
