The Diagnostic Inference Process, Informative Priors
Probability densities for high-precision (standard deviation 10 mm Hg) (A) and low-precision (standard deviation 30 mm Hg) (B) measurements of blood pressure for Gaussian prior densities. (A,B1) show the assumed prior densities, (A,B2) show the posterior densities resulting from a single arterial pressure measurement of 25 mm Hg, (A,B3) show the posterior densities if subsequent to the initial measurement, 1,500 ml of fluid are applied intravenously resulting in a pressure measurement of 30 mm Hg, while (A,B4) show the posterior densities if the measurement after fluid application is 70 mm Hg.
