Confidence intervals and sample sizes: don't throw out all your old sample size tables.
Over the past few years it has been recommended that emphasis be placed on the confidence interval rather than on hypothesis testing in the statistical analysis of medical data.'-3 Although the two methods approach the analysis and presentation of data differently and confidence intervals make assessment of results easier, differences in basic interpretation arise only in exceptional circumstan...

متن کاملConfidence Intervals for Lower Quantiles Based on Two-Sample Scheme
In this paper, a new two-sampling scheme is proposed to construct appropriate confidence intervals for the lower population quantiles. The confidence intervals are determined in the parametric and nonparametric set up and the optimality problem is discussed in each case. Finally, the proposed procedure is illustrated via a real data set.
متن کاملFinite Sample Differentially Private Confidence Intervals
We study the problem of estimating finite sample confidence intervals of the mean of a normal population under the constraint of differential privacy. We consider both the known and unknown variance cases and construct differentially private algorithms to estimate confidence intervals. Crucially, our algorithms guarantee a finite sample coverage, as opposed to an asymptotic coverage. Unlike mos...
