When the regressors of a econometric linear model are nonorthogonal, it is well known that their estimation by ordinary least squares can present various problems that discourage the use of this model. The ridge regression is the most…

An extraction of the top mass from cross section measurements in the dilepton and lepton+jets channels with an integrated luminosity of about 1fb-1 is given. Two ways are presented : one based on the simple lecture of the graph of the cross…
