I have data for the analysis and I need to present the fluctuation in the information. I’m using a histo with TH1D class and I’d like to show the RMS value for the data, not the Std Dev. The data haven’t a gaussian distribution, so the average isn’t zero. But If I choose GetRMS or GetStdDev I have the same value. When I looked at the TH1.h (line 316) documentation to read about the GetRMS method I see that the RMS call StdDev values.
I have many histo to generate. Is it possible to edit the class to implement this method?
