Explanation of confidence interval from R function boot.ci

WebThese results tell us that the 2.5 th percentile of the bootstrap distribution is at 0.19 years and the 97.5 th percentile is at 3.48 years. We can combine these results to provide a 95% confidence for μ Unattr - μ Ave that is between 0.19 and 3.48. We can interpret this as with any confidence interval, that we are 95% confident that the ... WebHowever, it's important to keep in mind that, like normal-based 95% CI, a bootstrap confidence interval is only guaranteed to have correct coverage asymptotically. One nice thing about working with the median or other quantiles is that you can construct exact finite sample confidence intervals under very weak assumptions.
