cdfkur: Cumulative Distribution Function of the Kumaraswamy Distribution
Description
This function computes the cumulative probability or nonexceedance probability
of the Kumaraswamy distribution given parameters ($\alpha$ and $\beta$) of the distribution computed
by parkur. The cumulative distribution function of the distribution is
$$F(x) = 1 - (1-x^\alpha)^\beta \mbox{,}$$
where $F(x)$ is the nonexceedance probability for quantile $x$,
$\alpha$ is a shape parameter, and $\beta$ is a shape parameter.
