the lower range reported for SMART/ALERT), we can calculate the posttest probability of anthrax with both positive and negative test results by using Bayes' theorem (40). We combined the individual projections derived from these different databases using Bayes' theorem, described previously (17,18) to yield a single prediction of carcinogenicity. Thus, they see Bayes' theorem as a mathematical expression of how people should think about events such as these. |
