Dear Root Authors
I am using the TEfficiency object to calculate the background acceptance rate of a selection. I’m using weighted events and the background MC statistics are very low (ie non-Gaussian) so I’m trying to use the Bayesian estimators.
Is there an easy way to retrieve the entire Bayesian posterior PDF from the TEfficiency object (as a TF1 or histogram for example) ?
I think a possible way to obtain this distribution would be to calculate the bounds for lots of different confidence intervals and try to reverse engineer the distribution that way, but I’m not certain that will work.
Thankyou.
