Significance of Lifetime Distribution for Estimating Average Lifetime of Products

Introducing a New Lifetime Distribution of Power Series Distribution of the Family Gampertz

In this Paper, We propose a new three-parameter lifetime of Power Series distributions of the Family Gampertz with decreasing, increasing, increasing-decreasing and unimodal Shape failure rate. The distribution is a Compound version of of the Gampertz and Zero-truncated Possion distributions, called the Gampertz-Possion distribution (GPD). The density function, the hazard rate function, a gener...

An Evaluation of the Systems Reliability Using Fuzzy Lifetime Distribution

A New Lifetime Distribution

Many if not most lifetime distributions are motivated only by mathematical interest. Here, a new three parameter distribution motivated mainly by lifetime issues is introduced. Some properties of the new distribution including estimation procedures are derived. Two real data applications are described to show superior performance versus at least seven of the known lifetime models.

A new lifetime distribution

A new two-parameter distribution with decreasing failure rate is introduced. Various properties of the introduced distribution are discussed. The EM algorithm is used to determine the maximum likelihood estimates and the asymptotic variances and covariance of these estimates are obtained. Simulation studies are performed in order to assess the accuracy of the approximation of the variances and ...
