Autor: M. Nagy, H. M. Barakat, M. A. Alawady, I. A. Husseiny, A. F. Alrasheedi, T. S. Taher, A. H. Mansi, M. O. Mohamed

Publikováno v: AIMS Mathematics, Vol 9, Iss 4, Pp 8311-8338 (2024)

This work utilizes generalized order statistics (GOSs) to study the $ q $-Weibull distribution from several statistical perspectives. First, we explain how to obtain the maximum likelihood estimates (MLEs) and utilize Bayesian techniques to estimate

Asymptotic behavior of ordered random variables in mixture of two Gaussian sequences with random index

Autor: H. M. Barakat, M. H. Dwes

Publikováno v: AIMS Mathematics, Vol 7, Iss 10, Pp 19306-19324 (2022)

When the random sample size is assumed to converge weakly and to be independent of the basic variables, the asymptotic distributions of extreme, intermediate, and central order statistics, as well as record values, for a mixture of two stationary Gau

Bootstrapping m-generalized order statistics with variable rank

Autor: H. M. Barakat, Magdy E. El-Adll, M. E. Sobh

Publikováno v: AIMS Mathematics, Vol 7, Iss 8, Pp 13704-13732 (2022)

In this paper, several bootstrap properties of m-generalized order statistics (m-GOSs) with variable rank (central and intermediate) are revealed. We study the inconsistency, weak consistency and strong consistency of bootstrapping central and interm

Limit Distributions of Ordered Random Variables in Mixture of Two Gaussian Sequences

Autor: H. M. Barakat, M. H. Dwes

Publikováno v: Journal of Mathematics, Vol 2022 (2022)

In this paper, we study the limit distributions of extreme, intermediate, and central order statistics, as well as record values, of the mixture of two stationary Gaussian sequences under equicorrelated setup.

Concomitants of Order Statistics and Record Values from Generalization of FGM Bivariate-Generalized Exponential Distribution

Autor: H. M. Barakat, E. M. Nigm, M. A. Alawady, I. A. Husseiny

Publikováno v: Journal of Statistical Theory and Applications (JSTA), Vol 18, Iss 3 (2019)

We introduce the generalized Farlie–Gumbel–Morgenstern (FGM) type bivariate-generalized exponential distribution. Some distributional properties of concomitants of order statistics as well as record values for this family are studied. Recurrence

Statistical modeling of extremes under linear and power normalizations with applications to air pollution

Autor: H. M. BARAKAT, E. M. NIGM, O. M. KHALED

Publikováno v: Kuwait Journal of Science, Vol 41, Iss 1 (2014)

In this paper the Block Maxima (BM) and the Peak Over Threshold (POT) methods are used to model the air pollution in two cities in Egypt. A simulation technique is suggested to choose a suitable threshold value. The validity of full bootstrapping tec
