In statistics, a confidence interval (CI) is a range of values used to estimate an unknown statistical parameter, such as a population mean. Rather than...

In statistics, a binomial proportion confidence interval is a confidence interval for the probability of success calculated from the outcome of a series...

called credible set or credible region. Credible intervals are a Bayesian analog to confidence intervals in frequentist statistics. The two concepts arise...

prediction interval bears the same relationship to a future observation that a frequentist confidence interval or Bayesian credible interval bears to an...

can be described by the confidence interval or CI. To show how a larger sample will make the confidence interval narrower, consider the following examples:...

The most prevalent forms of interval estimation are confidence intervals (a frequentist method) and credible intervals (a Bayesian method). Less common...

A tolerance interval (TI) is a statistical interval within which, with some confidence level, a specified sampled proportion of a population falls. "More...

probability, or coverage for short, is the probability that a confidence interval or confidence region will include the true value (parameter) of interest...

separate 95% confidence interval for each age. Each of these confidence intervals covers the corresponding true value f(x) with confidence 0.95. Taken...

allowing the construction of a z-test for hypothesis testing and confidence interval estimation. It is used in various fields to compare success rates...

can be estimated through the usage of a confidence interval known as a one-sample proportion in the Z-interval whose formula is given below: p ^ ± z ∗...

In statistics, Fieller's theorem allows the calculation of a confidence interval for the ratio of two means. Variables a and b may be measured in different...

each of these studies (often represented by a square) incorporating confidence intervals represented by horizontal lines. The graph may be plotted on a natural...

observation k from a Poisson distribution with mean μ, a confidence interval for μ with confidence level 1 – α is 1 2 χ 2 ( α / 2 ; 2 k ) ≤ μ ≤ 1 2 χ 2 (...

cumulative distribution function. To obtain a confidence interval for ρ, we first compute a confidence interval for F( ρ {\displaystyle \rho } ): 100 ( 1...

eventually obtained, i.e., if a high precision is required (narrow confidence interval) this translates to a low target variance of the estimator. the use...

data analysis framework that uses a combination of effect sizes, confidence intervals, precision planning, and meta-analysis to plan experiments, analyze...

nonparametric confidence intervals are a general class of confidence intervals around statistical functionals of a distribution. To calculate these confidence intervals...

event did not occur in a sample with n subjects, the interval from 0 to 3/n is a 95% confidence interval for the rate of occurrences in the population. When...

interval estimation: such interval estimates are typically either confidence intervals, in the case of frequentist inference, or credible intervals,...
