42. Program of disease diagnostics [№3 за 2009 год]
Authors: (l_jmoudiak@hotmail.com) - , Ph.D; (l_jmoudiak@hotmail.com) - , Ph.D;
Abstract: There was developed a methodic of diagnostics based on computation of diseases probabilities. This methodic is using multivariate distribution, repeatedly defined symptoms, analyses and other data, markers of viral hepatitis, etc – are considered. There was written a program that makes differential diagnostics between obstructive and hepatocellular jaundice with effectiveness 97 %.
Keywords: obstructive jaundice, hepatocellular jaundice, diagnostic signs, Bayes' formula, probability, diagnostics, diagnostics program
