متن کاملConfidence 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 کاملBOOTSTRAP CONFIDENCE INTERVALS 1 BootES : An R Package for Bootstrap Confidence Intervals on Effect Sizes
Bootstrap Effect Sizes (bootES; Gerlanc & Kirby, 2012) is a free, open source software package for R (R Development Core Team, 2012), which is a language and environment for statistical computing. BootES computes both unstandardized and standardized effect sizes (such as Cohen’s d, Hedges’s g, and Pearson’s r), and makes easily available for the first time the computation of their bootstrap CIs...
متن کاملConfidence intervals for the population mean tailored to small sample sizes, with applications to survey sampling.
The validity of standard confidence intervals constructed in survey sampling is based on the central limit theorem. For small sample sizes, the central limit theorem may give a poor approximation, resulting in confidence intervals that are misleading. We discuss this issue and propose methods for constructing confidence intervals for the population mean tailored to small sample sizes. We presen...
