In this article, based on progressively type-II censored schemes, the maximum likelihood, Bayes, and two parametric bootstrap methods are used for estimating the unknown parameters of the Weibull Fréchet distribution and some lifetime indices as rel

The Generalized r-Whitney Numbers

Autor: Beih S. El-Desouky, F. A. Shiha, Ethar M. Shokr

Publikováno v: Applied Mathematics. :117-132

In this paper, we define the generalized r-Whitney numbers of the first and second kind. Moreover, we drive the generalized Whitney numbers of the first and second kind. The recurrence relations and the generating functions of these numbers are deriv
