A model for collaboration networks giving rise to a power law distribution with exponential cutoff [PDF]

open access: yes, 2007
Recently several authors have proposed stochastic evolutionary models for the growth of complex networks that give rise to power-law distributions.

An Exponential Distribution with a Jump. [PDF]

open access: yesThe Egyptian Statistical Journal, 1997
In this paper, we study an exponential distribution with a jump at one. The moments and moment generating function of this distribution will be derived. Also, we will estimate the parameters of this distribution.

Extended Poisson Exponential Distribution [PDF]

open access: yes, 2015
A new mixture of Modified Exponential (ME) and Poisson distribution has been introduced in this paper. Taking the Maximum of Modified Exponential random variable when the sample size follows a zero truncated Poisson distribution we have derived the new ...

Statistical Properties and Applications of the Exponentiated Chen-G Family of Distributions: Exponential Distribution as a Baseline Distribution

open access: yesAustrian Journal of Statistics, 2022
In this work, the Exponentiated Chen-G family of distributions is studied by generalizing the Chen-G family of distributions through the introduction of an additional shape parameter. The mixture properties of the derived family are studied.

New Exponentiated Exponential- Rayleigh Distribution: Structure and Properties

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences
In this research, we will introduce a new distribution, which is called the new exponentiated exponential-Rayleigh distribution, which is built by adding the shape parameter to the cumulative function of the exponential-Rayleigh distribution resulting ...

Reconsideration of sample size and power calculation for overall survival in cancer clinical trials

open access: yesContemporary Clinical Trials Communications, 2018
When designing a cancer clinical trial, it is usual to assume an exponential distribution for a time-to-event outcome such as overall survival (OS). OS is often expressed as the sum of progression-free survival (PFS) and survival post-progression (SPP ...

Statistical Modeling using A New Hybrid Form of The Inverted Exponential Distribution with Different Estimation Methods

open access: yesInPrime, 2022
This paper introduces a new four-parameter distribution called the exponentiated Gompertz generated inverted exponential (EGGIE) distribution. Explicit expressions of the structural properties such as the ordinary and incomplete moments, probability ...

A Characterization of the Exponential Distribution

open access: yesThe Annals of Mathematical Statistics, 1963
This paper continues a study, initiated in [1], of the stochastic independence of $V = X - Y$ and the mean of order $\gamma$, \begin{equation*}\tag{1}M_\gamma\begin{align*} = (1/\gamma) \log \lbrack(e^{\gamma X} + e^{\gamma Y})/2\rbrack\quad\text{for} \gamma \neq 0 \text{and} \gamma \neq \pm \infty\\ = (X + Y)/2\quad\text{for} \gamma = 0\\ = \max (X, Y)

The Exponentiated Kumaraswamy-Exponential Distribution

open access: yesBritish Journal of Applied Science & Technology, 2015
A new continuous distribution called exponentiated Kumaraswamy-exponential that extends the exponential distribution and some other distributions is proposed and studied. Several structural properties of the new distribution were investigated, including the moments, hazard function, mean deviations and Rényi entropy.
