The Kumaraswamy distribution is one of these distributions which is particularly useful to many natural phenomena whose outcomes have lower and upper bounds or bounded outcomes in the biomedical and epidemiological research. As a motivation to our current work, we consider a financial risk modeling scenario. Based on this distribution, we propose a generalization of the Kumaraswamy distribution refereed to as the exponentiated Kumaraswamy distribution. 0000024917 00000 n 48 69 0000087837 00000 n xref 0000064041 00000 n "Estimation of reservoir yield and storage distribution using moments analysis".

Assume that Xa,b is a Kumaraswamy distributed random variable with parameters a and b. ○   Wildcard, crossword Here, we propose two new defective distributions: the Kumaraswamy Gompertz and Kumaraswamy inverse Gaussian distributions, extensions of the Gompertz and inverse Gaussian distributions under the Kumaraswamy family of distributions. One may introduce generalised Kuramaswamy distributions by considering random variables of the form , with and where denotes a Beta distributed random variable with parameters and . 0000020042 00000 n You can also try the grid of 16 letters. It is similar to the Beta distribution, but much simpler to use especially in simulation studies due to the simple closed form of both its probability density function and cumulative distribution function. 0000104529 00000 n We propose a new generator of continuous distributions with at least four positive parameters called the Kumaraswamy-Odd Rayleigh-G family. In Sect. The Kumaraswamy distribution was developed by Indian hydrologist Poondi Kumaraswamy in a paper published in 1980 as a generalized distribution suitable for describing hydrological random variables not typically well-served by classical or empirical probability distributions. Choose the design that fits your site. The Kumaraswamy distribution is very similar to the Beta distribution, but has the important advantage of an invertible closed-form cumulative distribution function. 4 we describe the relationships between the shapes of the re-parameterized A windows (pop-into) of information (full-content of Sensagent) triggered by double-clicking any word on your webpage. 0000013031 00000 n Density, distribution function, quantile function and random generation for the Kumaraswamy distribution.
