The Coherence Principle: A Falsifiable Prior for Model Selection from the Grammar of Theories
Raul Jimenez, Carlos Peña Garay, Fergus Simpson +1
Bayesian model selection in cosmology and particle physics is often performed where posterior odds inherit a strong, often unacknowledged dependence on the prior assigned to compet…
