I am fitting a variable Bmass with double gaussian+exponential. I want to check the fit quality. Could you please tell me how to print the chi square/dof in the fitted plot? I also want to plot pull distributions for the fit plot. How to plot pull distribution?
However, it doesn’t know how many parameters the fitted function had. That’s why you have to give this as a hint for the internal calculation.
I updated the documentation, so it will show up much more clearly on the webpages in a couple of days.
