Abstract:

This is the fifth in a series of experiments on Bayesian diagnostic systems. In this experiment two procedures for obtaining a posteriori P HD probability estimates were compared under conditions of low fidelity of input data and various levels of time-stress. In one procedure a computer aggregated the subjects a priori P DH estimates. In the alternate procedure the a posteriori probabilities were estimated by the subjects without computer aid. The results favor the computer-aided procedure and tend to support the use of automated Bayesian hypothesis-selection procedures in diagnostic systems. Author
