Description
Those lectures are intended as the first part of a wider tutorial aiming at the use of RooFit and RooStats. The purpose is to present selected statistics topics used for LHC data analysis manageable with RooFit and RooStats toolkits that will be presented on November 26 and 27 2009 EVO: Statistical methods (Universe)
