....the Nuclear Medicine Department between 1991 and 1994. We selected only the patients with complete diagnostic procedures (all four levels) 6] For determining the pre test probability we applied a tabular calculation, consisting of three attributes (age, sex, type of chest pain) retrieved from [9]. What is small enough depends on the problem and is calculated by internal leave one out testing 3. Results We performed all our experiments by using naive Bayesian classifier [4] as our ML tool of choice, since it usually performs very well in medical problems and can comprehensibly ....

For each patient, the table was indexed by a subset of signs and symptoms attributes (age, sex, type of chest pain) The aim of our early studies [6, 7] was to improve the diagnostic performance (sensitivity and specificity) of non invasive diagnostic methods (i.e. clinical ex Table 1.
