cdfkap: Cumulative Distribution Function of the Kappa Distribution
Description
This function computes the cumulative probability or nonexceedance probability
of the Kappa of the distribution computed by parkap. The cumulative distribution function is
where \(F(x)\) is the nonexceedance probability for quantile \(x\),
\(\xi\) is a location parameter, \(\alpha\) is a scale parameter,
\(\kappa\) is a shape parameter, and \(h\) is another shape parameter.
Usage
cdfkap(x, para)
Value
Nonexceedance probability (\(F\)) for \(x\).
Arguments
x
A real value vector.
para
The parameters from parkap or vec2par.
