Calculating confidence intervals in R is a handy trick to have in your toolbox of statistical operations. A confidence interval essentially allows you to estimate about where a true probability is based on sample probabilities at a given confidence level compared to your null hypothesis. The confide...
In elementary statistics, the normal distribution is often used to find confidence intervals. But in reality, most of these intervals are found using the t-distribution — especially if you are working with small samples. Contents (Click to Skip to Section) What is a Confidence Interval? How ...

How to produce confidence intervals instead of confidence tricks: Representative sampling for molecular simulations of fluid self-diffusion under nanoscale... In particular, we show that these correlations can lead to confidence intervals on the fluid self-diffusion coefficient that are dramatically ...
Simulation studies of confidence-interval procedures often only report coverage rates. This is not sufficient to judge whether the intervals are unbiased, that is, whether they are equally likely to be above as below the true value if they do not cover the true value. Most procedures suggest th...
The biggest misconception regarding confidence intervals is that they represent the percentage of data from a given sample that falls between the upper and lower bounds. In other words, it would be incorrect to assume that a 99% confidence interval means that 99% of the data in a random sampl...

When the size of population or its subsets is small, a sample survey often cannot provide proper confidence intervals of proportions. In our practice, this kind of problem is too serious to keep silence. This article discuses the problems occurring in estimating confidence intervals when population...
