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 $${\displaystyle 1-\alpha }$$. The … See more In statistics, a binomial proportion confidence interval is a confidence interval for the probability of success calculated from the outcome of a series of success–failure experiments (Bernoulli trials). … See more The Wilson score interval is an improvement over the normal approximation interval in multiple respects. It was developed by See more The arcsine transformation has the effect of pulling out the ends of the distribution. While it can stabilize the variance (and thus confidence intervals) of proportion data, its use has been criticized in several contexts. Let X be the … See more The rule of three is used to provide a simple way of stating an approximate 95% confidence interval for p, in the special case that no … See more A commonly used formula for a binomial confidence interval relies on approximating the distribution of error about a binomially-distributed observation, $${\displaystyle {\hat {p}}}$$, … See more The Jeffreys interval has a Bayesian derivation, but it has good frequentist properties. In particular, it has coverage properties that are similar to those of the Wilson interval, but it is one of the few intervals with the advantage of being equal-tailed (e.g., … See more Let p be the proportion of successes. For 0 ≤ a ≤ 2, This family is a … See more
