Hello!
I’m trying to fit different data distribution with the same fit function.
The fits seem to be good, but the chi squares/ndf are not good.
I attach my code here. Someone could help me?
Thank you in advance,
Silvia

Hi,
I see you are getting very small chi2 value. this is because the fit errors you are using are overestimated (too large) compared to the real statistical fluctuations
