Differentiation between two diseases using a programmable hand-held calculator and Bayes' theorem: application to Crohn's disease and ulcerative colitis.
A short general program is presented for the Hewlett-Packard HP-41C programmable pocket calculator that calculates posterior probabilities of two diseases on the basis of frequencies of nosographic characteristics using Bayes' theorem. Extended memory and functions modules allow the storage of many data in an ASCII file.
