variance

• variance(a: number, b: number): number

• Returns the variance 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

  Example

  var v = variance( 0, 1 );
  // returns ~0.25

  Example

  var v = variance( 4, 12 );
  // returns ~6.667

  Example

  var v = variance( -4, 4 );
  // returns ~6.667

  Example

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

  Example

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

  Example

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

  Example

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