Hadron spectroscopy is one of many examples in physics which require complex statistical modeling. Large data sets reveal ever more structures of the underlying physical processes and their backgrounds. This drives the development of more advanced models, simultaneously making it difficult to gauge improvements in data description and inference quality. There is a variety of different criteria available to compare the performance of statistical models. We discuss the utility and validity of some of these criteria for the analysis of hadron spectroscopy data. Where possible we verify them on simulated data and compare the implications of their underlying assumptions.
