Dear Rooters,
I am frequently asked about the fit parameters errors given in
the statistics/fit info box. People claim that the correlations
in between parameters are not included in the parametors errors.
Is it right?
>From the screen output of the fit parameters, it is not clear to
me whether the diogonal elements of the error matrix are the only
ones taken into account (thus meaning no correlation taken into
account).
Well, I was just looking into the TMinuit class, source file
section, seems to be the case.
Thanks for your help,
Guy.
