Erlang distribution

The Erlang distribution is a two-parameter family of continuous probability distributions with support . The two parameters are: * a positive integer the "shape", and * a positive real number the "rate". The "scale", the reciprocal of the rate, is sometimes used instead. The Erlang distribution with shape parameter simplifies to the exponential distribution. It is a special case of the gamma distribution. It is the distribution of a sum of independent exponential variables with mean each.
