Hello All,
I am a bit unsure how to perform a TTree::UnbinnedFit. The documentation says “For the fit to be meaningful, the function must be self-normalized”. I am unsure how to do this.
What should my fit function look like if, for example, when binned, the histogram looks like a Gaussian sitting on a flat DC background:
A*NormailsedGausssian + DC
is not “self-normalized”
Cheers
Andrew
