Introduction to Generalized Linear Models

Introduction Generalized Linear Models Structure For example, a common remedy for the variance increasing with the mean is to apply the log transform, e.g. log( yi) = 0 + 1 x 1 + i) E (log Y i) = 0 + 1 x 1 This is a linear model for the mean of log Y which may not always be appropriate. E.g. if Y is income perhaps we are really interested

Poisson Models for Count Data

4.1 Introduction to Poisson Regression As usual, we start by introducing an example that will serve to illustrative regression models for count data. We then introduce the Poisson distribution and discuss the rationale for modeling the logarithm of the mean as a linear function of observed covariates. The result is a generalized linear model with
