Introductory Statistics School 2013

18 Mar 2013, 08:00 → 22 Mar 2013, 18:00 Europe/Berlin

Building 1b, SR 4 (DESY Hamburg)

Christoph Rosemann (DESY Hamburg), Gero Flucke (DESY), Olaf Behnke (DESY), Stefan Schmitt (DESY), Thomas Schoerner-Sadenius (DESY)

The school aims at providing education for the selected statistics-related tasks and methods for physics data analysis in the LHC era. It is mainly targeted at Master and young Ph.D. students.
The program comprises lectures and tutorials on the following topics:
- Parameter estimation and fitting techniques
- Hypothesis tests
- Limit determination
- Systematic uncertainties
and concludes with a practical analysis walk-through.
