Applications include probabilistic assessment of the time between arrivals of patients to the emergency room of a hospital, and time between arrivals of ships at a particular port. Comments: Itis a special case of Gamma distribution. You might like to use Exponential Density to perform your computations, and Lilliefors Test for Exponentiality to perform the goodnessoffit test....
