Exponentiated Extended Weibull-Power Series Class of Distributions [PDF]

open access: yes, 2015
In this paper, we introduce a new class of distributions by compounding the exponentiated extended Weibull family and power series family. This distribution contains several lifetime models such as the complementary extended Weibull-power series ...

Weibull, ��-Weibull and 3-parameter extended Weibull distributions

open access: yes, 2022
Here we will consider a function of -statistics, the -Weibull distribution, and compare it to the well-known Weibull distribution. The -Weibull will be also compared to the 3-parameter extended Weibull function, obtained according to the Marshall Olkin extended distributions.
