The other day someone mentioned my complaint about the Wikipedia article on “Bayesian inference” (see footnote 1 of this article) and he said I should fix the Wikipedia entry myself.
And so I did. I didn’t have the energy to rewrite the whole article–in particular, all of its examples involve discrete parameters, whereas the Bayesian problems I work on generally have continuous parameters, and its “mathematical foundations” section focuses on “independent identically distributed observations x” rather than data y which can have different distributions. It’s just a wacky, unbalanced article. But I altered the first few paragraphs to get rid of the stuff about the posterior probability that a model is true.
I much prefer the Scholarpedia article on Bayesian statistics by David Spiegelhalter and Kenneth Rice, but I couldn’t bring myself to simply delete the Wikipedia article and replace it with the Scholarpedia content.
Just to be clear: I’m not at all trying to disparage the efforts of the Wikipedians. It’s only through putting stuff out there that it can be edited and improved.
