| cdfkap {lmomco} | R Documentation |
This function computes the cumulative probability or nonexceedance probability
of the Kappa distribution given parameters (xi, α, and kappa, h) of the distribution computed
by parkap. The cumulative distribution function of the distribution is
F(x) = (1-h(1-frac{kappa(x-xi)}{α})^{1/kappa})^{1/h} mbox{,}
where F(x) is the nonexceedance probability for quantile x, xi is a location parameter, α is a scale parameter, kappa is a shape parameter, and h is another shape parameter.
cdfkap(x, para)
x |
A real value. |
para |
The parameters from parkap or similar. |
Nonexceedance probability (F) for x.
