Cumulative Distribution Function of the Asymmetric Triangular Distribution
Description
This function computes the cumulative probability or nonexceedance probability of the Asymmetric Triangular distribution given parameters (\nu
, \omega
, and \psi
) computed by partri
. The cumulative distribution function is
F(x) = \frac{(x - \nu)^2}{(\omega-\nu)(\psi-\nu)}\mbox{,}
for x < \omega
,
F(x) = 1 - \frac{(\psi - x)^2}{(\psi - \omega)(\psi - \nu)}\mbox{,}
for x > \omega
, and
F(x) = \frac{(\omega - \nu)}{(\psi - \nu)}\mbox{,}
for x = \omega
where x(F)
is the quantile for nonexceedance probability F
, \nu
is the minimum, \psi
is the maximum, and \omega
is the mode of the distribution.
