Combining the diagnostic accuracy of two analytes: I have two unrelated analytes [A and B] measured on the same individuals, which can each differentiate between normal and abnormal outcomes. The AUC from ROC analysis is 79% and 81% for A and B analytes. How can I combine the results of performance of both A and B to see if the AUC increases further, to improve the diagnostic accuracy, using STATA 8.2 Joe Onwude Springfield Hospital, Chelmsford, UK * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
