• mean(d1: number, d2: number): number

• Returns the expected value of an F distribution.

  Notes

  Parameters

  • d1: number

    numerator degrees of freedom

  • d2: number

    denominator degrees of freedom

  Returns number

  expected value

  Example

  var v = mean( 3.0, 5.0 );
  // returns ~1.667

  Example

  var v = mean( 4.0, 12.0 );
  // returns ~1.2

  Example

  var v = mean( 8.0, 4.0 );
  // returns 2.0

  Example

  var v = mean( 1.0, -0.1 );
  // returns NaN

  Example

  var v = mean( -0.1, 1.0 );
  // returns NaN

  Example

  var v = mean( 2.0, NaN );
  // returns NaN

  Example

  var v = mean( NaN, 2.0 );
  // returns NaN
