Binomial exact confidence interval

WebThe Wilson score interval is a simple and accurate confidence interval for the binomial proportion parameter, that automatically adjusts near the boundaries of the range. The Clopper–Pearson interval is an early and very common method for calculating binomial confidence intervals. This is often called an 'exact' method, as is attains the nominal coverage level in an exact sense, meaning that the coverage level never is less than the nominal . The Clopper–Pearson interval can be written as or equivalently,

The binomial confidence interval is a measure of uncertainty for a proportion in a statistical population. It takes a proportion from a sample and adjusts for sampling error.
