Conditioning on posterior samples for flexible frequentist goodness-of-fit testing
Ritwik Bhaduri, Aabesh Bhattacharyya, Rina Foygel Barber +1
Tests of goodness of fit are used in nearly every domain where statistics is applied. One powerful and flexible approach is to sample artificial data sets that are exchangeable wit…
