Finally, some multivariate generalizations of the Kumaraswamy Weibull distribution are discussed. Give contextual explanation and translation from your sites ! Thus, the sine Kumaraswamy-G family of distributions remains new in the literature and deserves a complete study, which is the aim of this paper. an offensive content(racist, pornographic, injurious, etc. The plots of the Kumaraswamy Odd Rayleigh Log-Logistic (KORLL) distribution indicate that the distribution can take many shapes depending on the parameter values. We show in fact that if a distribution is defective, then its extension under the Kumaraswamy family is defective too. 0000010287 00000 n

In Section 5, the usefulness of this distribution is illustrated by means of two real life data sets. 0000007469 00000 n
Assume that Xa,b is a Kumaraswamy distributed random variable with parameters a and b. The parameterization of the distribution in terms of shape parameters and the lack of simple expressions for its mean and variance hinder, however, its utilization with modeling purposes. In addition, the moments, skewness, and kurtosis are found. 0000017018 00000 n

English thesaurus is mainly derived from The Integral Dictionary (TID). As a motivation to our current work, we consider a financial risk modeling scenario. The latter exhibits many similarities to the beta distribution and a number of advantages in terms of tractability which has been discussed by Jones [5]. 0000020042 00000 n

1 Introduction We introduce a new ﬁve-parameter distribution, so-called generalized Kumaraswamy (GKw) distribution, which contains some well-known distributions as special sub-modelsas, for example, the Kumaraswamy (Kw) and beta (B) distributions. It was introduced by Kumaraswamy [4]. Previous article in issue; Next article in issue; 1. 0000007358 00000 n

One has the following relation between Xa,b and Y1,b. 0000087837 00000 n
This makes it much better suited than the Beta distribution for computation-intensive activities like simulation modeling and the estimation of models by simulation-based methods. However, in general the cumulative distribution function does not have a closed form solution. Then Xa,b is the a-th root of a suitably defined Beta distributed random variable.

Kumaraswamy was interested in distributions for hydrological random variables and actually proposed a mixture of a probability mass, F 0, at zero and density over (0, 1), although I am using the terminology ”Kumaraswamy’s distribution” to refer solely to the latter.
Fletcher, S.G., and Ponnambalam, K. (1996). 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.

We propose a new class of continuous distributions called the generalized Kumaraswamy-G family which extends the Kumaraswamy-G family defined by Cordeiro and de Castro [1]. Then Xa,b is the a-th root of a suitably defined Beta distributed random variable. 0000106209 00000 n

The English word games are: Kumaraswamy distribution Where do you meet this distribution? To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares. tion; Kumaraswamy distribution; Maximum likelihood; McDonald Distribution; Moments. The Kumaraswamy distribution is very similar to the Beta distribution, but has the important advantage of an invertible closed form cumulative distribution function. In this article, the five-parameter beta Kumaraswamy exponential distribution (BKw-E) is introduced, and some characterizations of this distribution are obtained. Fletcher, S.G., and Ponnambalam, K. (1996). "Improved point estimation for the Kumaraswamy distribution". (2011). The Kumaraswamy distribution has been used as a natural alternative to the beta distribution and has received great attention in statistics in the past few years, mainly due to the simplicity and the great variety of forms it can assume.
