Course content
In regression analysis, we examine the relationship between a random response variable and several other explanatory variables. In this class, we consider the theory of linear regression with one or more explanatory variables. Moreover, we also study robust methods, generalized linear models, model choice, highdimensional linear models, nonlinear models and nonparametric methods. Several numerical examples will illustrate the theory. You will learn to perform a regression analysis and interpret the results correctly. We will use the statistical software R to get handson experience with this.

First lecture on September 22nd
The first lecture is on Thursday, September 22nd, starting at 14:15 in HG E 1.1. 
Frequency of lectures and exercises
There will be a lecture every Monday at 10:15 in ML D 28. Lectures and exercises alternate on Thursdays at 14:15 in HG E 1.1. Exercises and will take place each second week, starting on on September 29th. Exceptions will be announced during the lecture and on this website. 
Content of the first exercises session
The first exercise session will include an introduction to the statistical programming language R with some exercises. In the exercise sessions, you can solve the R problems, the series and ask questions. You need to bring your own laptop for solving the R questions. 
Recording of lectures
The lectures will not be streamed via Zoom. The lectures will be recorded and uploaded to the ETH video portal after each lecture.

Software
Examples in the lecture as well as solutions to the exercises will be based on the statistical software R. R is a freely available open source program that works on all platforms and has become worldwide standard for data analysis. It can be downloaded from CRAN. An R Tutorial can be found here. The most commonly used editor for R is RStudio which can be downloaded from here.
Exercise classes
Exercise classes will take place every other week on Thursdays. The first exercise class on September 29th will feature an R tutorial with some exercises. Please install R and RStudio and bring your laptop to the exercise classes.
Series
If you are a PhD student who needs ETH credit points, the submission of four exercise series is mandatory. If this applies to you, please contact the assistant.
