(i.e., why does this distribution exist?) When should Gamma distribution be used for modeling? 1. Why did we invent Gamma distribution? Answer: To predict the wait time until future events. Hmmm ok, but I thought that’s what the exponential distribution is for. Then, what’s the difference between exponential distribution and gamma distribution? The exponential distribution predicts the wait time
