Generalized Linear Models in R

Let’s take a look at the generalized linear models in R.

We'll cover the following

Generalized linear models (GLMs)

Generalized linear models (GLMs)

GLMs were first proposed by Nelder and Wedderburn in the early 1970s, and (McCulloch & Nedler 1983)McCulloch, P. & Nelder, J. Generalized Linear Models. Chapman & Hall 1983. is the standard reference. GLMs have the following three components:

A linear predictor.
A variance function.
A link function.
