This paper presents the sequential statistical test used for selection of the most accurate subset of diagnostic tests. The proposed method is based on interative application of Z-test which compares areas under ROC (AUC) assessed for multiple diagnostic tests. Usage of the nonparametric method for estimation of AUC allows to apply this method for small numbers of patients.
