The Exponentiated Poisson-Lindley Distribution; Features and Applications in Reliability
author
Abstract:
Abstract. In this paper a new three-parameter lifetime distribution named “the Exponentialed Lindley-Poisson (E-LP) distribution” has been suggested that it has an increasing, decreasing and invers bathtube hazard rate depending on the parameter values. The (E-LP) distribution has applications in economics, actuarial modeling, reliability modeling, lifetime and queuing problems and biological sciences. Firstly, the mathematical and statistical characteristics of the proposed distribution are presented, then the applications of the new distribution are studied using the real data set. expressions for moments, skewness and kurtosis have been given. Various mathematical and statistical properties of the proposed distribution have been discussed. Estimation of its parameter has been discussed using the method of maximum likelihood. A simulation study is given. In the end, two applications of the new distribution have been discussed with two real lifetime data sets. The results also confirmed the suitability of the presented models for real data collection.

Exponentiated power Lindley distribution
A new generalization of the Lindley distribution is recently proposed by Ghitany et al. [1], called as the power Lindley distribution. Another generalization of the Lindley distribution was introduced by Nadarajah et al. [2], named as the generalized Lindley distribution. This paper proposes a more generalization of the Lindley distribution which generalizes the two. We refer to this new genera...

full textThe Lindley-Poisson distribution in lifetime analysis and its properties
In this paper, we introduce a new compounding distribution, named the LindleyPoisson distribution. We investigate its characterization and statistical properties. The maximum likelihood inference using EM algorithm is developed. Asymptotic properties of the MLEs are discussed and simulation studies are performed to assess the performance of parameter estimation. We illustrate the proposed model...
full textThe Beta-Lindley Distribution: Properties and Applications
We introduce the new continuous distribution, the so-called beta-Lindley distribution that extends the Lindley distribution. We provide a comprehensive mathematical treatment of this distribution. We derive the moment generating function and the rth moment thus, generalizing some results in the literature. Expressions for the density, moment generating function, and rthmoment of the order stati...
full textReliability Equivalence Factors in Exponentiated Exponential Distribution
The reliability equivalence factors of parallel system with n independent and identical components will be discussed. The failure rates of the system components are functions of time and follow the exponentiated exponential distribution. We shall introduce two different methods to improve the system designs. The first is the reduction method and the second is called redundancy method which is c...
