Pre-PHYSTAT RooStats Tutorial

Friday 14 Jan 2011, 08:00 → 18:00 Europe/Zurich

30/7-018 - Kjell Johnsen Auditorium (CERN)

This tutorial is closed to ATLAS, and will have an informal workshop-like feel. We will do our best to broadcast over EVO, but the room does not have a nice setup for that. BRING YOUR LAPTOP! In the afternoon, there is time for small groups to work on using the tools for real world analyses. So bring your histograms, ntuples, and questions. We will broadcast to EVO, but the room isn't really designed for it, so no promises. ****** NEW EVO Meeting******** Community: ATLAS Password: roostats Meeting Access Information: - Meeting URL http://evo.caltech.edu/evoNext/koala.jnlp?meeting=M2MvMB2v2sDaDn9M9lDM92
