In a research paper accepted for publication in Monthly Notices of the Royal Astronomical Society, they took data from WMAP and other cosmology experiments and analyzed it using Bayes's theorem, which can be used to show how the certainty attached to a particular conclusion is affected by different starting assumptions.
Bayes's theorem is commonly applied to medical diagnostic testing; in the context of evaluating diagnostic tests, the probability of a given individual having a disease depends both upon (1) an individual's prior probability of having the disease (usually determined from a base rate appropriate to the individual's risk group) and (2) the result of a diagnostic test.
