Symmetric Intervals and Confidence Intervals
Biometrical Journal, 1994AbstractWe show that the symmetric “confidence intervals” of WESTLAKE (1972, 1976), widely used and referred to in bioequivalence studies, are not confidence intervals in any accepted sense. Nevertheless, meaningful symmetric intervals can be constructed in the context of Bayesian or fiducial inference.

Confidence Intervals for a Proportion
Biometrika, 1956Tables of confidence intervals for a proportion based on the sample proportion are presented, calculated by a slight modification of the method proposed by Sterne (1954), for fixed sample sizes up to 30 and confidence coefficients of 0 90, 0 95 and 0 99. This system is compared, especially in shortness, with Sterne's system, Clopper & Pearson's (1934),

Bootstrap confidence intervals
Statistics & Probability Letters, 1988Abstract Nonparametric confidence bounds are obtained for a wide class of statistics using bootstrap. These results improve the errors in the probability estimates of the confidence intervals over the ones obtained by the normal approximation theory unconditionally.

1998
In the previous topic you began a study of the important and widely used technique of confidence intervals. These procedures use a sample statistic to estimate a population parameter with an interval of values and a certain confidence level. This topic asks you to continue this study by considering sample survey results and the connection between ...

Understanding confidence intervals
BMJ, 2014Researchers investigated the effects of controlled cord traction in the third stage of labour on postpartum haemorrhage when carried out in a high resource setting. A randomised controlled trial study design was used. Control treatment was standard placenta expulsion (awaiting spontaneous placental separation before facilitating expulsion). The setting

Fuzzy Sets and Systems, 1983
Fuzzy numbers have heretofore been conceived simply as convex fuzzy subsets of the real line, especially in the context of possibility theory. This paper proposes an alternative interpretation of fuzzy numbers: fuzzy confidence intervals. This number concept is particularly appropriate to problems of optimization with a fuzzy objective function or ...

Simultaneous confidence intervals
Scandinavian Actuarial Journal, 1966Abstract Let x = (x 1 ..., x n)′ be an n-dimensional normally distributed stochastic vector with mean m = (m 1 ..., m n)′ belonging to a subspace M of Rn and with covariance matrix C. It is well known how to obtain simultaneous confidence intervals for a class of linear functionals of the mean in different contexts.
