"Description": "Functions to assess the calibration of logistic regression\nmodels with the GiViTI (Gruppo Italiano per la Valutazione\ndegli interventi in Terapia Intensiva, Italian Group for the\nEvaluation of the Interventions in Intensive Care Units - see\n) approach. The approach\nconsists in a graphical tool, namely the GiViTI calibration\nbelt, and in the associated statistical test. These tools can\nbe used both to evaluate the internal calibration (i.e. the\ngoodness of fit) and to assess the validity of an externally\ndeveloped model.",
