 `calzone` is a comprehensive Python package for calculating and visualizing various metrics to assess the calibration of probabilistic models.
 To accurately assess the calibration of machine learning models, it is essential to have a comprehensive and reprensative dataset with sufficient coverage of the prediction space. The calibration metrics is not meaningful if the dataset is not representative of true intended population.
