Webb3 juni 2016 · In this article, we employ moment generating functions (mgf’s) of Binomial, Poisson, Negative-binomial and gamma distributions to demonstrate their convergence to normality as one of their parameters increases indefinitely. The motivation behind this work is to emphasize a direct use of mgf’s in the convergence proofs. WebbSolution.
