I use one detector like Scintillator, Aerogel Cherenkov counter.
When I get the total number of events N and the observed number of passed events k with cut condition, I can define efficiency.
But I don’t know how to calculate Efficiency error.
I think TEfficiency method can calculate this, but I found method using two histogram.
If I have three data set (cut, N, k) instead of histgram.
How do I use TEfficiency and get efficincy error?
Please help me.
