Webbobject (the Probability Integral Transform or PIT; see Eq.1) can favor pathological but un-informative PDFs (Schmidt et al.,2024). Moreover, overall uniformity of PIT values is possible even if particular subsets of the same test data are poorly-calibrated (Zhao et al.,2024). If the PDFs are well-calibrated, then the distribution of the PIT ... WebbPerson as author : Pontier, L.
