Hyper-Erlang_distribution Knowpia

In probability theory, a hyper-Erlang distribution is a continuous probability distribution which takes a particular Erlang distribution E_i with probability p_i. A hyper-Erlang distributed random variable X has a probability density function given by

A(x)=\sum _{i=1}^{n}p_{i}E_{l_{i}}(x)

where each p_i > 0 with the p_i summing to 1 and each of the E_{l_i} being an Erlang distribution with l_i stages each of which has parameter λ_i.^[1]^[2]^[3]
