Receiver operating characteristic laboratory (ROCLAB): Software for developing decision strategies that account for uncertainty

Receiver operating characteristic (ROC) methodology evaluates how well a decision strategy classifies retrospective dichotomous or fuzzy events. It also provides a rational basis for designing decision strategies for classifying prospective events. ROCLAB is a public domain software package written in Microsoft QuickBASIC for PC microprocessors that computes ROC functions and their useful derived features for discrete and fuzzy class membership data. Decision strategies that account for uncertainties related to prevalence, false classification costs, and fuzzy class membership are easily constructed with ROCLAB. ROC methodology is explained and ROCLAB features are demonstrated with examples from clinical medicine.<
