Webof the iterated bootstrap confidence interval. The scheme may be applied, simply and without any adaptation, to construct a confidence interval for any parameter of interest. The performance of the sequential iterated bootstrap confidence interval is illustrated on two examples involving the ratio of two population means and a population variance. WebIn the case of coverage correction in confidence intervals, bootstrap iteration is directed at obtaining intervals with high coverage accuracy. We consider several other properties …
