Estimating the expected value and variance of SDT indexes with heterogeneous individuals

Several methods of calculating the variance of the more popular parametric indexes of signal detection theory (SDT) have been proposed. Miller’s exact method and Gourevitch and Galanter’s approximate method have proved appropriate for most practical situations using yes–no detection paradigms. Those methods, specifically developed for single-point estimates, are also useful for a sample of estimates that share their parametric values of...
