    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.

    en.wikipedia.org/wiki/Coverage_probability

    The construction of binomial confidence intervals is a classic example where coverage probabilities rarely equal nominal levels. [3] [4] [5] For the binomial case, several techniques for constructing intervals have been created. The Wilson score interval is one well-known construction based on the normal distribution. Other constructions ...

    Confidence bands can be constructed around estimates of the empirical distribution function.Simple theory allows the construction of point-wise confidence intervals, but it is also possible to construct a simultaneous confidence band for the cumulative distribution function as a whole by inverting the Kolmogorov-Smirnov test, or by using non-parametric likelihood methods.

  6. Edwin Bidwell Wilson - Wikipedia

    en.wikipedia.org/wiki/Edwin_Bidwell_Wilson

    In Wilson (1927) he introduced the Wilson score interval, a binomial proportion confidence interval, and also derived the "plus four rule", which uses a pseudocount of two (add two to both your count of successes and failures, so four total) for estimating the probability of a Bernoulli variable with a confidence interval of two standard ...

  7. Confidence interval - Wikipedia

    en.wikipedia.org/wiki/Confidence_interval

    The confidence interval can be expressed in terms of statistical significance, e.g.: "The 95% confidence interval represents values that are not statistically significantly different from the point estimate at the .05 level." [20] Interpretation of the 95% confidence interval in terms of statistical significance.

    NEXT surveyed 1,500 small business owners aged 18-64 across industries and regions in late October and November 2024 to share findings about how economic factors are shaping business in the new year.

  9. Cumulative frequency analysis - Wikipedia

    en.wikipedia.org/wiki/Cumulative_frequency_analysis

    The Wilson score interval [12] provides confidence interval for binomial distributions based on score tests and has better sample coverage, see [13] and binomial proportion confidence interval for a more detailed overview. Instead of the "Wilson score interval" the "Wald interval" can also be used provided the above weight factors are included.
