New formulas to handle uncertainty from limited Monte Carlo statistics — •Thorsten Glüsenkamp for the IceCube collaboration — FAU Erlangen-Nürnberg, Erlangen, Bayern

This talk will discuss new probabilistic approaches to handle the statistical uncertainty from Monte Carlo statistics for Poisson likelihoods. First, it will be shown how five approaches from the last 25 years, starting with Barlow/Beeston in 1993, are related to each other. Then, the approaches are compared in a typical Toy MonteCarlo setting representatative of high-energy particle experiments. The results indicate the advantages of the new formulas over the old ones in terms of speed, interpretability, and ability to mitigate the statistical bias.
