To move from Bayes’ physical analogy to the application of Bayes’ Theorem in more general statistical inference, the physical randomness of Bayes’ ball must be translated into an epistemological statement of ignorance. This translation is in some sense philosophical rather than purely mathematical, and as such its viability is open to some debate. The second issue closely follows: in the absence of any knowledge or information about the parameter, is it appropriate to assume the prior distribution is uniform?

De Moivre did not seek to improve on Halley’s mortality table. Rather, his objective was to show how Halley’s work could be more readily applied to the valuation of annuities by reducing the computational burden associated with calculating annuity prices from age-specific mortality rates. Halley himself had pointed out in his Breslau paper that the calculation of annuity prices from the mortality rates of his table ‘will without doubt appear to be the most laborious calculation’ and noted that the production of the annuity table in his paper was ‘the short result of a not ordinary number of arithmetical operations’.
