Law of poisson
WebPoisson processes are often used to develop probabilistic models for \(N(t)\); in this context, the actual arrival times of the customers form a Poisson point process. We will consider a few different ways of defining and constructing Poisson processes, all of which give a process with the same law, but each description will have certain advantages over … Web19 dec. 2024 · Wageningen University & Research.
