WebFeb 27, 2024 · A Poisson Regression model is a Generalized Linear Model (GLM) that is used to model count data and contingency tables. The output Y (count) is a value that follows the Poisson distribution. It assumes the logarithm of expected values (mean) that can be modeled into a linear form by some unknown parameters. Webmod1 <- glm (incident ~ 1, offset=patients.on.ward, family=binomial) the offset represents trials, incident is either 0 or 1, and the probability of an incident is constant (no heterogeneity in tendency to generate incidents) and patients do not interact to cause incidents (no contagion).
