 This distinction should not be confused with that between objective and subjective probability. Both physical and epistemic probability can be given an objective and subjective character, in the sense that both can be taken as dependent or independent of a knowing subject and her conceptual apparatus. For more details on the interpretation of probability, the reader is invited to consult Galavotti (2005), Gillies (2000), Mellor (2005), von Plato (1994), the anthology by Eagle (2010), the handbook of Hajek and Hitchcock (forthcoming), or indeed the entry on   interpretations of probability. In this context the key point is that the interpretations can all be connected to foundational programmes for statistical procedures. Although the match is not exact, the two major types specified above can be associated with the two major theories of statistics, classical and Bayesian statistics, respectively.
