Rationality[edit]

All this stuff about Bayesian inference being the model of rationality is ignorant nonsense.

I clarified this more than a year ago, with in-line cites to the highest quality most reliable sources, and the clarification remains in the article, which I suppose was intolerable.

I don't understand how people can write an article that is shown to be patent nonsense by the later discussion in the same article.  Kiefer.Wolfowitz 17:11, 26 February 2012 (UTC)

The article has now been changed, but I would mention that nowhere did previously it state that Bayesian inference was "the" model of rationality. The previous lead read "how the degree of belief in a proposition might change due to evidence." and that it is "a model of rational reasoning". Later on, we have "The philosophy of Bayesian probability claims". None of these suggest that Bayes' theorem is the sole theory of rationality. It was simply keeping the information relevant to the article, rather than expanding on other possible theories and techniques. Maybe the issue is that this simply was not sufficiently emphasised.

Before my edits, the article's lede asserted uniqueness of Bayesian updating as the rational system.  Kiefer.Wolfowitz 21:26, 26 February 2012 (UTC)
What the article said is that the philosophy of Bayesian probability asserts that this method of updating is the rational one. The distinction seems clear to me. Removing citation needed tag, obviously it is rational in the sense that sophisticated reason underlies the decision.73.2.136.228 (talk) 00:19, 2 October 2014 (UTC)

Updating[edit]

In the end I can only find arguments of why Bayesian updating is not the only rational rule, but I am still left wondering what bayesian updating actually is. Could anyone please fill the section with appropriate content? Thanks Elferdo (talk) 14:00, 14 October 2015 (UTC)

Section "Multiple observations" - conditional independence vs independence[edit]

In the current version (17 Jun 2016), the section "Multiple observations" requires "a sequence of independent and identically distributed observations" while the key to combine multiple observations is conditional independence as confirmed two lines below by the equation .

Examples: contrast with frequentist approach[edit]

For the 'Examples', I think it would be useful to contrast this approach with a frequentist approach. This would be especially interesting if the frequentist approach used a different formula, yielded a different result, or was not calculable. Conversely, for the current 'Probability of a hypothesis' example I am thinking there is negligible difference to a frequentist approach.
