WebJan 13, 2024 · Example 1 A book contains 500 pages. If there are 200 typing errors randomly distributed throughout the book, use the Poisson distribution to determine the probability that a page contains a. exactly 3 errors, b. at least 3 errors, c. at most 2 errors, d. 2 or more errors but less than 5 errors. Solution WebThe fitting of y to X happens by fixing the values of a vector of regression coefficients β. In a Poisson Regression model, the event counts y are assumed to be Poisson distributed, which means the probability of observing y is a function of the event rate vector λ.
