| Table 2: Inference of the ROC curve by the semiparametric least squares based method (OLS) with different choices of the false positive sets (OFP: observed false
positive fraction, EF: equal fraction or MP: midpoint method). Cases and controls are drawn from normal distributions. (α0, α1) = (1.2, 0.45). (nD, nD) = (100, 100). Sample
means and sampling standard errors from 1000 simulations are shown. |
