Overview:  OR-DBM MRMC 2.51 has the ability to perform both Dorfman-Berbaum-Metz (DBM) and Obuchowski-Rockette (OR) analyses for all three types of analyses: random readers and random cases, random readers and fixed cases, and fixed reader and random cases.  For the OR method three types of error covariance estimation can be selected: jackknife, bootstrap, or the method of DeLong et al (1988, Biometrics).  The program also allows for user-friendly “stacked” data entry format and the ability to export data in previous formats to the stacked format.

This software was developed as part of the Improved DBM ROC Methods in Diagnostic Radiology grant.
