# The Erlang(n) Distribution¤

Erlang distributions are a subset of the gamma distribution (see The Gamma Distribution screen in the Continuous Lifetime Distributions 2 session) where N is an integer. It is the distribution of the sum of exponentially-distributed random variates, and this will turn out to be important later.

They are a useful class of survival distributions as they are one of the few for which analytic calculations of M(t) can be done.
