This article deals with Bayesian inference and prediction of the inverse Rayleigh distribution. We first obtain Bayes estimators of the inverse Rayleigh parameter and its posterior expected loss based on a conjugate prior. Then we derive the highest posterior density (HPD) and equal-tail credible intervals for the inverse Rayleigh parameter, as well as consider Bayes prediction for future observation based on the observed sample and provide the equal-tail and HPD prediction intervals. Monte Carlo simulations are performed to compare the performances of the Bayes estimates under different situations. A real data example is provided to assess how the inverse Rayleigh distribution fits a real data set. In analyzing the data, we propose a graphical technique to choose the parameter values of the conjugate prior.
