mean ( number $a, number $b ) : number	Mean of the distribution

Method Details

CDF() public static method

cdf = 0 for x < a x - a cdf = ----- for a ≤ x < b b - a cdf = 1 x ≥ b

public static CDF ( number $a, number $b, number $x )
$a	number	lower boundary of the distribution
$b	number	upper boundary of the distribution
$x	number	percentile

PDF() public static method

1 pdf = ----- for a ≤ x ≤ b b - a pdf = 0 for x < a, x > b

public static PDF ( number $a, number $b, number $x )
$a	number	lower boundary of the distribution
$b	number	upper boundary of the distribution
$x	number	percentile

mean() public static method

a + b μ = ----- 2

public static mean ( number $a, number $b ) : number
$a	number	lower boundary of the distribution
$b	number	upper boundary of the distribution
return	number
