- To get a credit for the course students have to pass the midterm (1/3 of the total grade) and the final exam (2/3 of the total grade, please keep in mind that grades for the course must be rounded!).
You can take the final exam even if you have failed the midterm. You pass the course only once you have passed both parts. (E.g. you can pass the final in one year and the midterm in another year to get the credit.) You must be registered for the exam in Friedolin to get a credit for the course.
- Midterm (1/3):
- Thu., 22.11.2018, 18:00, Carl Zeiss Str. 3, HS 1[Friedolin]
- To register for the midterm students register for the course at least 10 days before the midterm exam through Friedolin. Please register for the course and for the exam! (If it is for some reason impossible to register for the exam during the first weeks of the term you can still take the midterm if you only register for the course. However, to take the final exam you have to register in Friedolin for the exam!)
- Exchange students who can not register for the course with Friedolin complete this form on their computer.
Students will also receive the midterm results (and, in case they failed, their seat for the resit) at their uni-jena address. Students who send their public PGP key to firstname.lastname@example.org before the midterm will receive their results encrypted to their key.
Candidates who have earlier passed either the midterm or the final but not both parts have two options for the exams they take this term:
- They register for the exam, but show up only for the part they did not pass in the past. In this case I will credit the result of the previous attempt of the other part for this term.
- They register for the exam, and show up for both parts, midterm and final. In this case the result of this term counts for the final result. (This holds even if this term's result is a fail!)
- Instructions for the midterm.
- Grades 22.11.2018:

- Resit of the midterm: Thu., 6.12.2018, 18:00, Carl Zeiss Str. 3, HS 3. [Friedolin]
- Students who took the midterm and who failed are automatically registered for the resit. No extra registration is needed in this case. (Please note that for the resit of the final exam you must register with the examination office.)
- Students who missed the first take because they were ill and who present a certificate from their physician within three days after the missed exam will participate in the resit. These students complete this form on their computer.
- Students who passed the first take can't take the resit.
- Students who did not show up for the first take and who were not ill don't take the resit.
- Step 1:
Please send an email with a brief list as text (such a list makes it much easier to give you informative feedback while still protecting your personal data) of the points you expect to obtain for each question to the office of the chair (please
include your name and your matriculation number, please do not include any scans or other attachments).
We will then compare your list with our list.
If you have given us a detailed list with your points for each question, and there are only one or two deviations, then we can give you informative feedback.
If you have not given us a detailed list with your points, then all we can normally do is tell you that after we checked your exam nothing changes. Of course, should we ever discover a mistake, we will fix it (the procedure seems to be quite reliable, so there are very, very few mistakes).
- Step 2: If we can not find a mistake in our grading and if you disagree, you can have a look at a copy of your solution. Here is a sample how (a part of) a graded solution might look like:
In this case please make an appointment with the office of the chair . You will need a photo ID as a proof of your identity. It will also help you if you have a copy of your questions and the solution sheet ready.
- Step 3: If you are still unsatisfied with your grade you can formally appeal the decision with the Prüfungsamt (examination office).
- Final exam (2/3):
- 18.02.2019, 10-12, Carl Zeiss Str. 3, HS 1.
You must register in Friedolin for the exam (not only for the course), even if you have passed the midterm earlier.
Exchange students who can not register for the course with Friedolin complete this form on their computer.
- Other material:
- Handout (contains all the slides):
- Previous exam questions
- Handout (contains all the slides):
- Basic mathematical and statistical methods as, e.g., in BW24.1.
To learn more, I recommend the following textbooks. You find further
recommendations at the end of each chapter in the handout. (If you find not enough copies of the books you need in the library, please tell the librarians.
If you do not tell them, nothing will change.)

- Examples from the lecture:
- In the lecture I will often use practical examples as illustrations.
I recommend that you try these examples on your own. To do this, open R and type the following:
data(Caschool,package="Ecdat")from now on all commands refer to this dataset, e.g.:
large<-factor(str>20)A brief documentation of the variables of this dataset can be obtained with
For our practical examples (during the entire course) we will use the software environment R. I think that it is helpful to coordinate on one environment and R has the advantage of being free and rather powerful.
For the Bayesian parts we will use JAGS. It helps if you have installed R and JAGS on your computer when we start the course.
- Documentation for R is
provided via the built in help system but also through the
- The R Guide, Jason Owen (Easy to read, explains R with the help of examples from basic statistics)
- Simple R, John Verzani (Explains R with the help of examples from basic statistics)
- Einführung in R, Günther Sawitzki (In German. Rather compact introduction.)
- Econometrics in R, Grant V. Farnsworth (The introduction to R is rather compact and pragmatic.)
- An Introduction to R, W. N. Venables und D. M. Smith (The focus is more on R as a programming language)
- The R language definition (Concentrates only on R as a programming language.)
- On the JAGS Homepage you go to the files pages, then to Manuals, to find the JAGS user manual.
- We will use the following packages:
AER, boot, bootstrap, calibrate, car, coda, Ecdat, geepack, Hmisc, lattice, latticeExtra, lme4, lmtest, MASS, memisc, nnet, plotrix, plyr, relaimpo, runjags, Sleuth2. If, e.g., the command
library(Ecdat)generates an error message (
Error in library(Ecdat): There is no package called 'Ecdat'), you have to install the package.
- Installing packages with Microsoft Windows:
Rgui.exeand install packages from the menu
Packages / Install Packages).
- Installing packages from advanced operating systems:
- From within R use the command
install.packages("Ecdat"), e.g., to install the package
- In the lecture we will use RStudio as a front end.
For the Bayesian part we will use the library
runjagsand the software

We try hard to avoid mistakes but if you think we made a mistake, please check first with the help of your problem sheet and the sample solution. Please keep in mind that the points given above are the minimum needed to obtain a certain grade. If you think we made a mistake, please proceed as follows:
