Some characterizations of the natural exponential families in R² and related Laplace transforms

Joanna Matysiak


We characterize some natural exponential families in R^2 via diagonal elements of quadratic variance function. Our proofs rely on Laplace transforms, and along the way, we obtain some new characterizations for Laplace transforms of probability measures in certain classes of functions.
