Example 2: Prey Capture Rate (3) Obviously this model is non-linear in its parameters, but, by using a reciprocal link, the right-hand side can be made linear in the parameters, 1 1 h 1 1 . Alternatively, you could think of GLMMs asan extension of generalized linear models (e.g., logistic regression)to include both fixed and random effects (hence mixed models). 3 0 obj << The second model, for the case of a binary response, is often called a logistic regression model.

First of all, the logistic regression accepts only dichotomous (binary) input as a dependent variable (i.e., a vector of 0 and 1). Linear regression is the most basic form of GLM. This book presents a greatly enlarged statistical framework compared to generalized linear models (GLMs) with which to approach regression modelling.
