Statistical methods in in bioinformatics-feb-18

Statistical methods in in bioinformatics

February 13th – 15th, 2018, Room 202, EMBL Heidelberg

Instructors: Bernd Klaus, bernd.klaus@embl.de, b-klaus.de .

This advanced course provides an overview of statistical methods that are
commonly used in the analysis of high throughput data sets. All methods
will be introduced using RNA-Seq (single cell and bulk) datasets.
A working knowledge of R is required for this course and can be obtained
via self learning using this material here:

No longer available (R intro materials)

The course should also be very suitable for people with some experience in another
scripting language like Python or Matlab. While the course focuses on R,
many of the techniques covered are also implementable in other scripting languages
like Python using e.g. the PANDAS, sklearn etc. modules.

The course will be a mix of lectures and hands-on training. Practicals will
consist of computer exercises that will enable the participants to apply statistical
methods to the analysis of data under the guidance of the lecturer and
possibly teaching assistants.

The course open to all at EMBL (including outstations) and free of charge.
