|Exam and lecture attestation (Testat)||
In order to obtain ECTS-credit points you
have to pass the written exam during the examination session. This
exam will include tasks to be solved on a computer with R. No course
attendance confirmation is required to subscribe for the exam. For
ECTS credits, you do not have to hand in your solution to the
exercises during the semester.
Doctoral students who need (part of the) credit points, but who do not require a grade should talk to Martin Mächler at the beginning of the semester. In that case you will need to solve and submit at least 70% of the exercises.
"Computational Statistics" deals with modern methods of data analysis (aka "data science") for prediction and inference. An overview of existing methodology is provided and also by the exercises, the student is taught to choose among possible models and about their algorithms and to validate them using graphical methods and simulation based approaches.Objective
Getting to know modern methods of data analysis for prediction and inference. Learn to choose among possible models and about their algorithms. Validate them using graphical methods and simulation based approaches.Course Synopsis
multiple regression, nonparametric methods for regression and classification (kernel estimates, smoothing splines, regression and classification trees, additive models, projection pursuit, neural nets, ridging and the lasso, boosting). Problems of interpretation, reliable prediction and the curse of dimensionality are dealt with using resampling, bootstrap and cross validation.Notice
Exercises will be based on the open-source statistics software R. Emphasis will be put on applied problems. Active participation in the exercises is strongly recommended.
Beginning of lecture: Thursday, 23/02/2017.
Exercises start on 24/02/2017 at 10:15 in room HG E 1.2, with a special introduction to the "R" software. Please bring a laptop. The tutorial can be downloaded here. Here are some further helpful links related to R:

The lecture notes are available here.
The recorded lectures can be found here. You need nethz login credentials to log in.
R Scripts as used in the lecture
A selection is online in this directory.
The course outline can be found here.
Exercise classes will be held weekly on Friday from 10.15 to 11:55 in HG E 1.2. For the precise dates see the table below.
The exercise class on Friday will be divided in 2 parts. During the first part, the assistant will discuss the new exercise series. Part of the material covered during the lecture can also be recapitulated if this is requested. During the second part, the assistant will answer individual questions (regarding the lecture, the exercise sheet or R) and give you back the corrected solutions you submitted the previous exercise class.
Questions and comments
You can always ask questions to the lecturer and tutors during the class and the exercise session. If you have concrete R questions, you can bring your own laptop to the exercise class and ask them directly to the assistant. If you want to send us an email, please send it to this address: firstname.lastname@example.org. Please do not send any R code to this address, it is usually easier to answer these questions during the exercise class or to arrange an appointment.
The new exercise sheet will always be uploaded on the Thursdays preceding the corresponding preliminary discussion session.
We will correct your answers given that you respect our hand-in policy:
No R script files and no lengthy compilations of
outputs or figures.
- Only hand in your most important findings and answers. Do not include your code unless the question specifically asks to fill in a given skeleton of an R code.
Focus on the interpretation of the results.
- We are usually more interested in what you conclude based on the obtained results, than on the numbers per se.
Hand in by 12pm (noon) on due date.
- The solved exercises should be handed in during the exercise class or placed in the corresponding tray in HG J68 on the due date by 12pm at the latest.
A very elegant way to hand in your solution is to combine everything in a single file (for example by generating a pdf with LATEX or Word/Libreoffice). An easy way to do this is to use R-Markdown! See the tutorial and the template.

Help with R
On Friday, February 24st 2017, there will be an introduction to the statistical software R during the exercise class from 10:15 to 11:55. The tutorial can be downloaded here. Here are some further helpful links related to R:
