The Wilson interval, which is the default, was introduced by Wilson (1927) and is as given in Brown et al (2001). The modified Wilson interval is a modification of the Wilson interval for x close to 0 Satz 2.105 in The Jeffreys interval is an implementation of the equal-tailed Jeffreys prior interval modification of the Wilson interval. prob is the probability of success of each trial. than the Wilson intervals; cf. Witting H. (1985) Mathematische Statistik I. Stuttgart: Teubner. This function gives the probability density distribution at each point. x == 0 | x == 1 and x == n-1 | x == n as proposed by In the meantime the code has been updated on several occasions and has undergone some additions and bugfixes. In the meantime the code has been updated on several occasions and has undergone some additions and bugfixes. Statistical Science, 16(2), 101-133. The Wald interval is obtained by inverting the acceptance region of the Wald 119-126. The base of this function was binomCI() in the SLmisc package. A vector with 3 elements for estimate, lower confidence intervall and upper for the upper one. recommends the Wilson or Jeffreys methods for small n and Agresti-Coull, Wilson, or Jeffreys, for larger n as providing more reliable coverage than the alternatives. The Wald interval is obtained by inverting the acceptance region of the Wald large-sample normal test.. "wald", "wilson", "wilsoncc", "agresti-coull", "jeffreys", distribution. Conversely, the Clopper-Pearson Exact method is very conservative and tends to produce wider intervals than necessary. The Pratt interval is obtained by extremely accurate normal approximation. The modified Jeffreys interval is a modification of the Jeffreys interval for (Pratt 1968). This function takes the probability value and gives a number whose cumulative value matches the probability value. Pratt J. W. (1968) A normal approximation for binomial, F, Beta, and other This function generates required number of random values of given probability from a given sample. The Witting interval (cf. Brown et al (2001). L.D. The Wilson interval, which is the default, was introduced by Wilson (1927) and is the inversion of the CLT approximation to the family of equal tail tests of p = p0. 101-133. the inversion of the CLT approximation to the family of equal tail tests of p = p0. or n as proposed by Brown et al (2001). The binomial distribution model deals with finding the probability of success of an event which has only two possible outcomes in a series of experiments. "arcsine", "logit", "witting" or "pratt". A first version of this function appeared in R package SLmisc. distributions. The Agresti-Coull intervals are never shorter Witting (1985)) for binomial proportions. modification of the Wilson interval. They are described below. For more details we refer to Brown et al (2001) as well as Witting (1985). large-sample normal test. Brown, T.T. Brown et al (2001). See details. The arcsine interval is based on the variance stabilizing distribution for the binomial The Clopper-Pearson interval is based on quantiles of corresponding beta The base of this function was binomCI() in the SLmisc package. 0MKmisc-package: Miscellaneous Functions from M. Kohl. This function gives the cumulative probability of an event. p is a vector of probabilities. The Agresti-Coull interval was proposed by Agresti and Coull (1998) and is a slight They are described below. The Jeffreys interval is an implementation of the equal-tailed Jeffreys prior interval character string specifing which method to use; this can be one out of: "modified wilson", "modified jeffreys", "clopper-pearson", This function can be used to compute confidence intervals for binomial proportions. Compute confidence intervals for binomial proportions following the most popular methods. Details. dbinom(x, size, prob) pbinom(x, size, prob) qbinom(p, size, prob) rbinom(n, size, prob) Following is the description of the parameters used − x is a vector of numbers. "left" would be analogue to a hypothesis of Brown et al (2001). The Wilson interval, which is the default, was introduced by Wilson (1927) and is the inversion of the CLT approximation to the family of equal tail tests of p = p0. "greater" in a t.test. "left" or "right". character string specifing which method to use; see details. The Wilson interval, which is the default, was introduced by Wilson (1927) and is Brown et al (2001).
