Implementing a 3D histogram version of the Energy-Test in ROOT

摘要

Comparing simulation and data histograms is of interest in nuclear and particle physics experiments; however, the leading three-dimensional histogram comparison tool available in ROOT, the 3D Kolmo-gorov-Smirnov test, exhibits shortcomings. Throughout the following, we present and discuss the implementation of an alternative comparison test for three-dimensional histograms, based on the Energy-Test by Asian and Zech.
