In this paper we dene and study a new three-parameter lifetime model called the Burr X Frechet distribution. The new model has the advantage of being capable of modeling various shapes of aging and failure criteria. Various of its properties including ordinary and incomplete moments, quantile and generating functions, Renyi and -entropies and order statistics are derived. The maximum likeli- hood method is used to estimate the model parameters. Simulation results to assess the performance of the maximum likelihood estimation are discussed. We prove empirically the importance and exibility of the new model comparing it with other extensions of the Frechet distribution in the existing literature.
