I am Marios and i am newbie. I use root lately and have some questions.
i wanted to get rms/covariance/correlation/mean for a TGraphErrors . Looking at Class TGraphErrors i did not find something but while i was keep looking i discovered these information at Histograms( TH1). Then i tried (e.g. TGrapherrors->getRMS )and it worked even if it is not written at the class reference of TGraphErrors. Do you know why couldn’t i find them?maybe i was searching the wrong way? or maybe there is another class reference for these?
i also need the errors to these quantities.The information exists for histograms but this time it doesn’t work for graph. Is there some way to do this?
Any help would be appreciated,
Thank you very much,
