WebThe Hypoexponential distribution is the distribution of the sum of n ≥ 2 independent Exponential random variables. This distribution is used in moduling multiple exponential stages in series. This distribution can be used in many domains of application. In this paper we consider the case of n exponential Random Variable having distinct parameters. The following probability distributions are all considered special cases of a continuous phase-type distribution: • Degenerate distribution, point mass at zero or the empty phase-type distribution – 0 phases. • Exponential distribution – 1 phase.
