independent Poisson random variables with means λ(tn+1 −tn). Note that properties (i) and (iii) imply that N(t) is Poisson with mean λt . Example. Customers arrive at a shop as a Poisson process with rate 20 per hour. In a half-hour period, calculate the probability that 4 customers arrive in the first 15 minutes and 6 in the next 15 minutes.

If you specify the poisson option, ci means assumes count data and computes exact Poisson confidence intervals. Example 4: Poisson confidence intervals We have data on the number of bacterial colonies on a Petri dish. The dish has been divided into 36 small squares, and the number of colonies in each square has been counted. Each observation in

The Poisson distribution is a probability distribution of a discrete random variable that stands for the number (count) of statistically independent events, occurring within a unit of time or space (Wikipedia-Poisson, 2012), (Doane, Seward, 2010, p.232), (Sharpie, De Veaux,
