pdfkur: Probability Density Function of the Kumaraswamy Distribution
Description
This function computes the probability density
of the Kumaraswamy distribution given parameters (\(\alpha\) and \(\beta\)) computed by parkur. The probability density function is
$$f(x) = \alpha\beta x^{\alpha - 1}(1-x^\alpha)^{\beta-1} \mbox{,}$$
where \(f(x)\) is the nonexceedance probability for quantile \(x\),
\(\alpha\) is a shape parameter, and \(\beta\) is a shape parameter.
Usage
pdfkur(x, para)
Value
Probability density (\(f\)) for \(x\).
Arguments
x
A real value vector.
para
The parameters from parkur or vec2par.
