Hi Antonio,
very nice study (except for the yields). Looking at the errors
for the different scale factors you can see that the error scales with the
scaling factor. Well, this is clear from the definition of the chi^2
function. At least this is what we expected. So we have to find out, how
to apply the scaling for the likelihood fit.
Just two more comments:
- the scale factor of 100 is quite big, if you redo anything, please use
10.
- for the strange numbers of the yields, can you just rerun the default
value and change from the chi^2 to the likelihood fit using
RooMinuit m(nll)?
Cheers,
Wolfgang
