Chapter 4 Poisson Models for CountDataIn this chapter we study log-linear Models for Count data under the assump-tion of a Poisson error structure. These Models have many applications, notonly to the analysis of counts of events, but also in the context of Models forcontingency tables and the analysis of survival Introduction to Poisson RegressionAs usual, we start by introducing an example that will serve to illustrativeregression Models for Count data. We then introduce the Poisson distributionand discuss the rationale for modeling the logarithm of the mean as a linearfunction of observed covariates.
distribution if you consider the distribution of the number of successes in a very large number of Bernoulli trials with a small probability of success in each trial. Speci cally, if Y ˘B(n;ˇ) then the distribution of Y as n!1 and ˇ!0 with = nˇremaining xed approaches a …
