On estimation of stress–strength reliability with log-Lindley distribution

Abstract

The log-Lindley distribution was recently introduced in the literature as a viable alternative to the Beta distribution. This distribution has a simple structure and possesses useful theoretical properties relevant in insurance. Classical estimation methods have been well studied. We introduce estimation of parameters from Bayesian point of view for this distribution. Explicit structure of stress–strength reliability and its inference under both classical and Bayesian set-ups is addressed. Extensive simulation studies show marked improvement with Bayesian approach over classical given reasonable prior information. An application of a useful metric of discrepancy derived from stress–strength reliability is considered and computed for two categories of firm with respect to a certain financial indicator.
