CDF() public static méthode

Cumulative distribution function Calculate the cumulative value value up to a point, left tail.
public static CDF ( number $x, number $x₀, integer $γ ) : number
$x number
$x₀ number location
$γ integer scale
Résultat number

        return 1 / $π * atan(($x - $x₀) / $γ) + 0.5;
