Exponentiated Weibull distribution

open access: yesStatistica, 2007
In this paper we study the family of distributions termed as exponentiated Weibull distribution. The distribution has three parameters (one scale and two shape) and the Weibull distribution and the exponentiated exponential distribution, discussed by ...

The Weibull-Geometric distribution [PDF]

open access: yesJournal of Statistical Computation and Simulation, 2008
In this paper we introduce, for the first time, the Weibull-Geometric distribution which generalizes the exponential-geometric distribution proposed by Adamidis and Loukas (1998).

Weibull Lindley Distribution

open access: yesRevstat Statistical Journal, 2018
A new distribution is introduced based on compounding Lindley and Weibull distributions. This distribution contains Lindley and Weibull distributions as special cases. Several properties of the distribution are derived including the hazard rate function,

Description of the statistical variations of the measured strength for brittle ceramics: A comparison between two-parameter Weibull distribution and normal distribution [PDF]

open access: yesProcessing and Application of Ceramics, 2020
It is generally assumed that the measured strength of brittle ceramics follows a Weibull distribution. However, there seems to be few sound and direct evidences to support this assumption.

Stochastic Stick - Slip Model Linking Crustal Shear Strength and Earthquake Interevent Times [PDF]

open access: yes, 2012
The current understanding of the earthquake interevent times distribution (ITD) is incomplete. The Weibull distribution is often used to model the earthquake ITD.

The Weibull-Gamma Distribution: Properties and Applications

open access: yesEntropy, 2019
A new member of the Weibull-generated (Weibull-G) family of distributions—namely the Weibull-gamma distribution—is proposed. This four-parameter distribution can provide great flexibility in modeling different data distribution shapes.

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.

On the gap between an empirical distribution and an exponential distribution of waiting times for price changes in a financial market [PDF]

open access: yes, 2006
We analyze waiting times for price changes in a foreign currency exchange rate. Recent empirical studies of high frequency financial data support that trades in financial markets do not follow a Poisson process and the waiting times between trades are ...

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 ...

Reliability analysis of structural ceramic components using a three-parameter Weibull distribution [PDF]

open access: yes, 1992
Described here are nonlinear regression estimators for the three-Weibull distribution. Issues relating to the bias and invariance associated with these estimators are examined numerically using Monte Carlo simulation methods.
