Figure 4From: A modified Wald interval for the area under the ROC curve (AUC) in diagnostic case-control studies Effect of variance heterogeneity. Box plot of the coverage probability for increasing variance of the cases σ 1 (variance of the controls σ 0 = 1,n = (40,100,200) and AUC 0 = (0.7,0.8,0.9), cross = median, box = 25%-75% quantile, whiskers = min - max).Back to article page
