MRMCaov: Multi-Reader Multi-Case Analysis of Variance

Getting Started

MRMCaov is an R package for statistical comparison of diagnostic tests - such as those based on medical imaging - for which ratings have been obtained from multiple readers and on multiple cases. Features of the package include the following.

Statistical comparisons of diagnostic tests with respect to reader performance metrics
Comparisons based on the ANOVA model of Obuchowski-Rockette and the unified framework of Hillis
Reader performance metrics for area under receiver operating characteristic curves (ROC AUCs), partial AUCs, expected utility of ROC curves, likelihood ratio of positive or negative tests, sensitivity, specificity, and user-defined metrics
Parametric and nonparametric estimation and plotting of ROC curves
Support for factorial, nested, and partially paired study designs
Inference for random or fixed readers and cases
Conversion of Obuchowski-Rockette to Roe, Metz & Hillis model parameters and vice versa
DeLong, jackknife, and unbiased covariance estimation
Compatibility with Microsoft Windows, MacOS, and Linux
