Английская Википедия:Hyper-Erlang distribution
Материал из Онлайн справочника
In probability theory, a hyper-Erlang distribution is a continuous probability distribution which takes a particular Erlang distribution Ei with probability pi. A hyper-Erlang distributed random variable X has a probability density function given by
- <math> A(x) = \sum_{i=1}^n p_i E_{l_i}(x)</math>
where each pi > 0 with the pi summing to 1 and each of the Eli being an Erlang distribution with li stages each of which has parameter λi.[1][2][3]
