For example, f(x) might be the proportion of people of a particular age x who support a given candidate in an election. If x is measured at the precision of a single year, we can construct a separate 95% confidence interval for each age. Each of these confidence intervals covers the corresponding true value f(x) with confidence 0.
[1] [2] The percentage, denoted (95% and 99% are typical values), is a coverage probability, called confidence level, degree of confidence or confidence coefficient; it represents the long-run proportion of CIs (at the given confidence level) that contain the true value of the parameter. For example, out of all intervals computed at the 95% ...

The probability density function (PDF) for the Wilson score interval, plus PDF s at interval bounds. Tail areas are equal. Since the interval is derived by solving from the normal approximation to the binomial, the Wilson score interval ( , + ) has the property of being guaranteed to obtain the same result as the equivalent z-test or chi-squared test.
An example forest plot of five odds ratios (squares, proportional to weights used in meta-analysis), with the summary measure (centre line of diamond) and associated confidence intervals (lateral tips of diamond), and solid vertical line of no effect. Names of (fictional) studies are shown on the left, odds ratios and confidence intervals on ...
The finite-sample distributions of likelihood-ratio statistics are generally unknown. [10] The likelihood-ratio test requires that the models be nested – i.e. the more complex model can be transformed into the simpler model by imposing constraints on the former's parameters.
An example of using Fleiss' kappa may be the following: consider several psychiatrists who are asked to look at ten patients. For each patient, 14 psychiatrists give one of possibly five diagnoses. These are compiled into a matrix, and Fleiss' kappa can be computed from this matrix (see example below ) to show the degree of agreement between ...
The name was eventually discontinued in 2008. Additionally, several of the Cartoon Network's original series have been produced by studios other than the network's own in-house studio. Notable examples are Ed, Edd n Eddy, Courage the Cowardly Dog, and Codename: Kids Next Door. The name was resurrected by the network in 2021 for a new animated ...
