This web book is the result of work of my colleagues Enrico Pegoraro, who wrote all previous versions of this book and Veronica Giro, who reviewed and reassembled all these materials.
However, it would not have been possible without the sharing of knowledge, information, ideas, doubts and even criticisms of many individuals on the internet. I would like to extend my sincere thanks to all of them.

About this manual

Many applications on statistical data are aimed to produce models that “describe” and try to “predict” the relationship between a set of explicative variables and one (or more) dependent variable.

Also when the goal of an analysis is not focused on describing or predict phenomena (as, for example, in ANOVA applications or in t-test), often “behind the scenes” a statistical model is the “core” of the analysis.

The analytical philosophy in R is then strongly model-oriented, also when it seems not.

The main aim of this manual is then on discovering modeling capabilities of R language via practical applications, and on approaching the main functions used to develop Linear Models (LM) and Generalized Linear Models (GLM).

The manual is split in four sections: Linear Models, Generalized Linear Models and Other Generalized Linear Models, Other models and Appendices.

Almost all sections initially show a theoretical introduction on the topic covered, and then several applied examples where many problems are addressed by means of models.

When and where

“Raccoon – Statistical Models with R” will be published one chapter a week in our Quantide blog.

It is part of our web-book project together with “Rabbit – Introduction to R” and “Ramarro – R for Developers”
