Abstract
It is often convenient to assume that X and X {pipe} Y are in the same exponential family. By considering X as the "parameter" and Y as the "data", the problem becomes determining which exponential families X {pipe} Y have conjugate priors. We develop a necessary condition for conjugacy. One-dimensional exponential families can be conjugate only if they have exactly two support points.
