Kumaraswamy Distribution
Description
Density, distribution function, quantile function and random generation for
Kumaraswamy distribution with shape
parameters.
Usage
dkd(x, lambda, alpha, log = FALSE)
pkd(q, lambda, alpha, lower.tail = TRUE, log.p = FALSE)
qkd(p, lambda, alpha, lower.tail = TRUE)
rkd(n, lambda, alpha)
Arguments
x , q |
vector of quantiles. |
alpha , lambda |
are non-negative shape parameters. |
log , log.p |
logical; if TRUE, probabilities p are given as log(p). |
lower.tail |
logical; if TRUE (default), probabilities are
|
p |
vector of probabilities. |
n |
number of observations. If |
Details
Kumaraswamy distribution with non-negative shape
parameters \alpha
and \lambda
has density
f\left( x\right) =\alpha \lambda x^{\lambda -1}\left( 1-x^{\lambda }
\right)^{\alpha -1},
where
0<x<1,~~\alpha ,\lambda >0.
Value
dkd
gives the density, pkd
gives the distribution
function, qkd
gives the quantile function and rkd
generates
random deviates.
