Value(s) for which log-probability is calculated. The Kumaraswamy distribution as defined by Ponndi Kumaraswamy (1980) in [6] has been identified as a viable alternative to Beta distribution because they both have the same basic shape properties (unimodal, uniantimodal, increasing, decreaing, monotone or constant) [4]. In 2011, [15] introduced the Kumaraswamy-G family of distribution. [3], Chang [4], Sinha et al. Kumaraswamy (1980) proposed and discussed a probability distribution for handling double-bounded random processes with varied hydrological applications. and the CDF is. It is very similar to the beta distribution but has a closed-form cdf given by G1(x;ω) = 1 −(1 −xα)β, 0 0. Keywords: Kumaraswamy distribution; Kumaraswamy-G Poisson distribution; Poisson distribution; Maximum likelihood estimation. Let T be a random variable with the Kumaraswamy’s distribution. Let T be a random variable which is continuous with probability density function (pdf) z(t) defined on the close interval [a,b]. and where a and b are non-negative shape parameters.. 70-81 Article Download PDF … import kumaraswamy. in R. Please help. A review of some of these generalizations is as listed: the ßeta generalized family (Beta-G) by Eugene et al. F(x | a, b) = 1 – (1 – x a) b. Cumulative distribution function. Introduction In order to meet scientific requirements, modern experiments require high precision in data analysis. Kumaraswamy Generalized distributions do not involve any special function like the incomplete beta function ratio; thereby, making it to be more tractable than the Beta Generalized family of distributions. The new distribution has a number of well-known lifetime special sub-models such as a new exponential type distribution, extension exponential distribution Kumaraswamy generalized exponential distribution, among several others. Note:-All materials will be revised shortly for the session 2018-19. (2002) and further discussed This paper is devoted to construct the maximum likelihood estimator of the lifetime performance index C L and the hypothesis testing technique for implementing C L under first‐failure progressive censoring sample from Kumaraswamy population. The PDF and CDF are defined, respectively, as r(t) = αβtα−1 1−tα β−1,0< t < 1, and (5) R(t) = 1− 1−tα β,0< t < 1, (6) The Kumaraswamy distribution on the interval (0,1), has its probability density function (pdf) and its cumulative distribution function (cdf) with two shape parameters a>0 and b>0 defined by f x a bx x I x F x x( ) = (1 ) (0 < <1) and ( ) =1 (1 ) .a ab−−11 − −− ab (1) If a random variable X has pdf given in eqn. In this paper, we introduce and study a new family of continuous distributions called Kumaraswamy Weibull-generated ( ) G KwW family of distributions which is an extension of the Weibull-G family of distributions proposed by Bourguignon in [3].
