Statistics Tools School 2011

4 Apr 2011, 13:00 → 8 Apr 2011, 12:30 Europe/Berlin

5th floor, Lorentz-Raum and Minkowski-Raum (Uni Mainz, Institut fuer Physik)

Frank Ellinghaus (University of Mainz), Gero Flucke (DESY), Stefan Tapprogge (Johannes Gutenberg-Universität Mainz), Thomas Schoerner-Sadenius (DESY)

The school aims at providing education for the most relevant statistics related tasks, problems and methods for physics data analysis in the LHC era. It is mainly targeted at Graduate (Diploma/Master) and PhD students. The sessions consist of lectures interleaved with "hands on" practical work (paper, computer exercises and/or tutorials). A guided tour to the MAMI accelerator and its experiments completes the program. The topics covered are: - General introduction: probabilities, basic distributions - Parameter estimation, likelihood fits, constrained fits - Limit determination - Data unfolding - Systematic uncertainties - Multivariate analysis techniques, TMVA - Optional: Bayesian Analysis Toolkit (BAT)
