Abstract:

Abstract. This talk presents an elementary informal technique for deriving the convergence of known discrete/continuous type distributions to limiting normal or non-normal distributions. The technique utilizes the ratio of the pmf/pdf at hand at two consecutive/nearby points. The technique does not furnish a formal proof for the convergence. It's a heuristic derivation technique only. We do provide, however, a framework for a formal method of proof. The presentation should be of interest to teachers and students of first year graduate level courses in probability and statistics.
