Purpose – The purpose of this paper is to present designs for an accelerated life test (ALT). Design/methodology/approach – Bayesian methods and simulation Monte Carlo Markov Chain (MCMC) methods were used. Findings – In the paper a Bayesian method based on MCMC for ALT under EW...

In this paper, we proposed a new two-parameter lifetime distribution with increasing failure rate. The new distribution arises on a latent complementary risk scenario. The properties of the proposed distribution are discussed, including a formal proof of its density function and an explicit...

In this paper we propose a new lifetime distribution which can handle bathtub-shaped, unimodal, increasing and decreasing hazard rate functions. The model has three parameters and generalizes the exponential power distribution proposed by Smith and Bain (1975) with the inclusion of an additional...
