The accuracy of the Normal or Poisson approximations can be significantly improved by adding part of an asymptotic expansion in the exponent. The signed-compound-Poisson measures obtained in this manner can be of the same structure as the Poisson distribution. For larger deviations we prove that signed-compound-Poisson measures enlarge the zone of equivalence for tails.
