Differentiation between diseases using a programmable hand-held calculator and Bayes' theorem: application to lower gastrointestinal tract disorders.
A program is presented for the Hewlett-Packard HP-41C programmable pocket calculator that computes posterior probabilities of more than 200 diseases on the basis of Bayes' theorem. Data for specific applications are stored in ASCII files. The program and data are retained in the non-volatile memory of the calculator. An example of the application of the program to six lower gastrointestinal tract disorders is given using data from the literature.
