Table 3.

Finite sample performance of the proposed CNA based estimators of accuracy for dependent censoring with 1 matched control under the F- and B-sampling. Shown below are the sample mean (Mean), standard error (SSE), average of the estimated standard error (ASE) and empirical coverage level of the 95% confidence intervals (CovP), multiplied by 100, for the proposed point and interval estimators.

(a) Accuracy Estimates at cp=F1(p), for k = 1, 2,3,4.
