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.
