Confidence intervals for relative difference in matching pairs under inverse sampling

In this paper, we have given four confidence intervals estimator for the relative difference in matching pairs under inverse sampling. The performance of the proposed methods is evaluated with respect to their coverage probability, expected widths and RNCP(the ratios of the mesial non-coverage probability to the non-coverage probability). Our empirical results show that the confidence intervals based on the wald statistic produce similar coverage probabilities with the pregiven confidence level and smaller confidence interval widths.
