Mixtures of exponential distributions and stochastic orders


  • Bartoszewicz, Jaroslaw


Mixtures of exponential distributions are treated as the Laplace transforms of mixing distributions. Using results on stochastic orders based on the Laplace transform order relations for the mixtures are derived. Preservation of some stochastic orders under the mixtures is studied.
