Suppose that has a Uniform distribution, that has the distribution on , and let . The resulting class of distributions of (as varies over all distributions on ) is called the Scale Mixture of Uniforms class of distributions, and the corresponding class of densities on is denoted by . We study maximum likelihood estimation in the family . We prove existence of the MLE, establish Fenchel characterizations, and prove strong consistency of the almost surely unique maximum likelihood estimator (MLE) in . We also provide an asymptotic minimax lower bound for estimating the functional under reasonable differentiability assumptions on in a neighborhood of . We conclude the paper with discussion, conjectures and open problems pertaining to global and local rates of convergence of the MLE.
