1. The Kumaraswamy-G Poisson Family of Distributions

Manoel Wallace A. Ramos, Pedro Rafael D. Marinho, Gauss M. Cordeiro, Ronaldo V. da Silva, G.G. Hamedani, Joao Pessoa
Pages: 222 - 239
For any baseline continuous G distribution, we propose a new generalized family called the Kumaraswamy-G Poisson (denoted with the prefix “Kw-GP”) with three extra positive parameters. Some special distributions in the new family such as the Kw-Weibull Poisson, Kw-gamma Poisson and Kw-beta Poisson distributions...

2. Concomitants of Dual Generalized Order Statistics from Bivariate Burr III Distribution

Haseeb Athar, Nayabuddin, Zuber Akhter
Pages: 240 - 256
In this paper probability density function of single concomitant and joint probability density function of two concomitants of dual generalized order statistics from bivariate Burr III distribution are obtained and expressions for single and product moments are derived. Further, results are deduced for...

3. Three Characterizations of Exponential Distribution Involving Median of Sample of Size Three

Marko Obradović
Pages: 257 - 264
In this paper three new characterizing theorems of exponential distribution are presented. They are based on equidistribution of some functions of order statistics. All of them include the median of sample of size three

4. A Lifetime Distribution Based on a Transformation of a Two-Sided Power Variate

Mustafa C. Korkmaz, Ali I. Genç
Pages: 265 - 280
We introduce a new generalization of Weibull distribution by making use of a transformation of the standard two- sided power distributed random variable. Weibull and the exponentiated Weibull distributions are submodels of this new distribution.We show that this newly defined distribution is in fact...

5. Approach of Reliability Approximation with Extent of Error for a Resistor under Weibull Setup

Sadananda Nayak, Dilip Roy
Pages: 281 - 288
Analytical determination of reliability of a complex system is item dependent and setup dependent and a very difficult task. In this paper we propose reliability approximation based on reliability bounds for one such engineering item - a Resistor with independent components having the Weibull distribution....

6. Goodness-of-fit tests for weibull populations on the basis of records

Mahdi Doostparast
Pages: 289 - 300
Record is used to reduce the time and cost of running experiments (Doostparast and Balakrishnan, 2010). It is important to check the adequacy of models upon which inferences or actions are based (Lawless, 2003, Chapter 10, p. 465). In the area of goodness of fit based on record data, there are a few...

7. Conditional risk estimate for functional data under strong mixing conditions

Abbes Rabhi, Sara Soltani, Aboubacar Traore
Pages: 301 - 323
We consider the problem of nonparametric estimation of the conditional hazard function for functional mixing data. More precisely, given a strictly stationary random variables Zi = (Xi; Yi)i2N, we investigate a kernel estimate of the conditional hazard function of univariate response variable Yi given...

8. Estimation of the Parameters of a Bivariate Geometric Distribution

U.J. Dixit, S. Annapurna
Pages: 324 - 349
The uniformly minimum variance unbiased estimators (UMVUE) of the parameters and reliability functions of a bivariate geometric distribution(BGD) have been derived.The exact variances of the maximum likelihood estimator (MLE) and of UMVUE have been derived and the corresponding mean square errors have...
