Purpose: To propose a new two-parameter lifetime distribution with increasing failure rate. Summary: The proposed distribution arises on a latent complementary risk scenario. The properties of the proposed distribution are discussed, including a formal proof of its probability density function and explicit algebraic formulae for its quantiles and survival and hazard functions. Also discussed are the inference aspects via Bayesian approach using Markov Chain Monte Carlo (MCMC) simulation. A simulation study investigates the frequentist properties under non informative priors. Some discussion on model selection criteria is provided. A real life illustration is included. (17 refs.)
