This paper introduces a new four-parameter lifetime model, which extends the Marshall-Olkin Fr�´echet distribution\nintroduced by Krishna et al. (2013), called the transmuted Marshall-Olkin Fr�´echet distribution. Various structural\nproperties including ordinary and incomplete moments, quantile and generating function, R�´enyi and q-entropies\nand order statistics are derived. The maximum likelihood method is used to estimate the model parameters. We\nillustrate the superiority of the proposed distribution over other existing distributions in the literature in modeling\ntwo real life data sets.
