The multiple-reader, multiple-case (MRMC) paradigm of Swets and Pickett (1982) for ROC analysis was expressed as a components of variance model by Dorfman, Berbaum, and Metz (1992) and validated by Roe and Metz (1997) for Type I error rates. Our group proposed an analysis of the MRMC components of variance model using bootstrap (Beiden, Wagner, and Campbell, 2000) experiments instead of jackknife pseudo-values. These approaches have been challenged by some contemporary authors (e.g. Zhou, Obuchowski, and McClish, 2002). The purpose of the present paper is to formally compare the models and to carry out validation tests of their performance. We investigate different approaches to statistical inference, including several types of nonparametric bootstrap confidence intervals and report on validation and simulation experiments of Type I errors.
