Generates pseudorandom numbers from Kumaraswamy Weibull Distribution.
Usage
rkwweibull(n, a, b, c, beta)
Arguments
n
Amount of generated numbers;
a
Shape parameter of the Kumaraswamy Weibull Distribution;
b
Shape parameter of the Kumaraswamy Weibull Distribution;
c
Shape parameter of the Kumaraswamy Weibull Distribution;
beta
Scale parameter of the Kumaraswamy Weibull Distribution.
Details
The Kumaraswamy Weibull Distribution function is given by:
$$F(x,a,b,c) = 1 - {1 - [1-e^{-(\beta*x)^c}]^a}^b$$
The distribution was proposed by Cordeiro, Ortega and Nadarajah in 2010 in the Journal of the Franklin Institute. The distribution is defined on the positive real ($x>0$). All parameters are also defined in the positive reals.
