Faraway (2005): Linear Models with R
This course offers a practically oriented introduction into regression modeling methods. The basic concepts and some mathematical background are included, with the emphasis lying in learning "good practice" that can be applied in every student's own projects and daily work life. A special focus will be laid in the use of the statistical software package R for regression analysis.Objective
The students acquire advanced practical skills in linear regression analysis and are also familiar with its extensions to generalized linear modeling.Content
The course starts with the basics of linear modeling, and then proceeds to parameter estimation, tests, confidence intervals, residual analysis, model choice, and prediction. More rarely touched but practically relevant topics that will be covered include variable transformations, multicollinearity problems and model interpretation, as well as general modeling strategies.
The last third of the course is dedicated to an introduction to generalized linear models: this includes the generalized additive model, logistic regression for binary response variables, binomial regression for grouped data and Poisson regression for count data.Notice
The exercises, but also the classes will be based on procedures from the freely available, open-source statistical software package R, for which an introduction will be held.

Exercises will be held roughly bi-weekly, see below. On these dates, the exercise classes will take place from 10:15 to 11:55 in HG E 1.2. The first exercise class is meant to be an opportunity for you to ask questions regarding the software R. The material you should be familiar with consists of the R tutorial and exercise sheet 1. Also further on, R will be used during the exercises so that you are expected to bring your laptop to the classes. Starting with the second exercise class, the idea is that there will be a discussion of the old exercise sheet (common problems) and a discussion of the new exercise sheet (hints and theory as needed) taking at most one hour. Afterwards, you work on the problems using the computer; the assistants will be there to give instructions and support.

Series and solutions
The solved exercises should be placed in the corresponding tray in HG J68 on the due date by 4pm at the latest. Only solutions to the exercises with your most important findings and answers shall be handed in, but no R script files and lengthy compilations of output or figures. It is much more important to give your understanding and interpretation of your findings than it is to provide many figures and numbers.

Help with R
During the first exercise class you will have the opportunity to ask questions regarding the software R. Further material can be found following the links below.
