摘要：

It is well-known that convergence of Laplace transforms in a neighbourhood of the origin is a sufficient criteria for weak convergence. It is worthwhile to note that the interior of the set of convergence points is convex. This provides a link to exponential family theory. As an example an autoregressive model is studied.
