Significance estimation using RooFit

ROOT
1

Dear All,

I hope I am in the right forum :confused: .

I would like to calculate significance of a certain mass distribution (data observed vs. bkg, no signal model in use), and I was following the RooFit manual to study the basic steps:
ftp://root.cern.ch/root/doc/RooFit_User … .91-33.pdf

However, the relevant section (14), is missing. Does any one knows if the manual has been updated since then?
Or, is there any other guide which explains thoroughly how to use RooFit or any other relevant tool for significance calculations for beginners [-o< ?

Thanks in advance

Hi,

For simple significance calculation you can use the RooStats classes, the ProfileLikelihoodCalculator or (better) the AsymptoticCalculator.
You can see an example in this tutorial
