| Abstract: | A model for an n-dimensional random vector which is the sum of v i.i.d. random variables with an exponential family distribution is considered. It is shown that the exact test can be approximated by a χ2-test as v → ∞. As an example a goodness-of-fit test for Poisson-distribution based on observed frequencies is derived. |
