by Ralf B. Schäfer, University of Koblenz-Landau, Winter Semester 2022/23
Note: As I have left the University of Koblenz-Landau (as of 1.1.2023 the RPTU Kaiserslautern-Landau), material on the university server such as videos and tutorials may stop working at some stage and this course will not be maintained anymore.
This repository provides all course materials including R code, slides and data as well as the links to teaching videos. Note that all material comes without guarantee! In case you have any comments regarding content, please feel free to contact me, but note that I generally do not respond to computer issues or questions for statistical advice (unless working on a joint publication).
To prepare your computer for the lecture, you need to install R and R Studio. I use several packages in the course, if you want to have all packages ready at the beginning of the course, run the script 0_install_packgs.R in the Code folder. Note that the course is work in progress and you should run this script again from to time to time to be up to date with the packages required. Alternatively, you can just install a new package whenever it is needed:
install.packages("package_name")

- Noel Juvigny-Khenafou is thanked for replacing me in teaching this lecture and dealing with the students (I was given partial teaching relief to join university management in the merger process with the TU Kaiserslautern).
- Achim Zeileis is thanked for development and support with the R exams package that is used for automated test generation in this course. Felix Högerl is thanked for help with exam evaluation.
- and of course a huge thanks to all the package authors and the whole R community as well as the stackexchange and stackoverflow community.
