# Showing that a Gamma distribution converges to a Normal distribution
Consider $$G = \operatorname{Gamma}(p)$$. As $$p$$ goes to $$\infty$$, the Gamma becomes more and more bell-shaped. How do I show that $$\frac{G - p}{\sqrt{p}} \to Z \sim N(0,1)$$ as $$p \to \infty$$?
I started with the CDF of the Gamma and began ... | {} |
