Introduction to Generalized Linear Models

Introduction Generalized Linear Models Structure Exponential Family Most of the commonly used statistical distributions, e.g. Normal, Binomial and Poisson, are members of the exponential family of distributions whose densities can be written in the form f (y ; ; ) = exp y b( ) + c(y; ) where is the dispersion parameter and is the canonical

Introduction to Structural Equation Modelling

Introduction to Structural-Equation Modelling 1 1. Introduction • Structural-equation models (SEMs) are multiple-equation regression models in which the response variable in one regression equation can appear as an explanatory variable in another equation.

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
