Bayes' Ratio: Dramatic Taxicab Example

This is a another short article on Bayesian odds, but in this case the author refers to Bayes' ratio instead. Bayes' theorem is used to derive a formula for the ratio of posterior probabilities \(P(A | C) / P(B | C)\) in terms of the prior probabilities \(P(A)\), \(P(B)\) and the conditional \(P(C | A)\) and \(P(C | B)\). An application is given to a taxi problem that is similar to the diagnostic testing setting. Unlike other Cut-the-Knot article, this one uses MathJax for the mathematical notation, so the notation is rendered nicely.
