S2 Topic 1: Binomial and Poisson distributions
Poisson experiment
The experiment is to run a Poisson process until time t. The arrivals are shown as red dots on a timeline, and the number of arrivals N is recorded on each update. The density and moments of N are shown in blue in the distribution graph and are recorded in the distribution table. On each update, the empirical density and moments are shown in red in the distribution graph and the moments are recorded in the distribution table. The parameters of the experiment are the rate of the process r and the time t, which can be varied with scroll bars.
