I’am doing a fit using roofit and the maximum likelihood. The fit result gives some parameters that I don’t understand.
The first is the EDM( estimated distance to minimum). My fit gives 2.64592e-05. I don’t know if it’s good or not.The second is the - Log (Likelihood), the value returned is -90999.
Other point: when you use the likelihood, the chi2/ndf is a good proof of the goodness of the fit ?
