An Elaboration on Sample Size Planning for Performing a One-Sample Sensitivity and Specificity Analysis by Basing on Calculations on a Specified 95% Confidence Interval Width [PDF]

open access: yesDiagnostics, 2023
Sample size calculation based on a specified width of 95% confidence interval will offer researchers the freedom to set the level of accuracy of the statistics that they aim to achieve for a particular study.

Confidence Interval Estimation of Interaction

open access: bronzeEpidemiology, 1992
Relative excess risk due to interaction, the proportion of disease among those with both exposures that is attributable to their interaction, and the synergy index have been proposed as measures of interaction in epidemiologic studies.

Coverage-adjusted confidence intervals for a binomial proportion [PDF]

open access: yesScandinavian Journal of Statistics, 41, 291-300 (2014), 2012
We consider the classic problem of interval estimation of a proportion $p$ based on binomial sampling. The "exact" Clopper-Pearson confidence interval for $p$ is known to be unnecessarily conservative.

Confidence with confidence intervals.

open access: yesIndian journal of ophthalmology, 1997
When considering the results of a study that reports one treatment to be better than another, what the practicing ophthalmologist really wants to know is the magnitude of the difference between treatment groups. If this difference is large enough, we may wish to offer the new treatment to our own patients.

On the Confidence Interval for the parameter of Poisson Distribution [PDF]

open access: green, 2000
The possibility of construction of continuous analogue of Poisson distribution with the search of bounds of confidence intervals for parameter of Poisson distribution is discussed.

Measurement of dispersion of PM 2.5 in Thailand using confidence intervals for the coefficient of variation of an inverse Gaussian distribution [PDF]

open access: yesPeerJ, 2022
Air pollution is a growing concern for the general public in Thailand with PM 2.5 (particulate matter ≤ 2.5 µm) having the greatest impact on health. The inverse Gaussian (IG) distribution is used for examining the frequency of high concentration events ...

Confidence Interval Based Distributionally Robust Real-Time Economic Dispatch Approach Considering Wind Power Accommodation Risk

open access: yesIEEE Transactions on Sustainable Energy, 2021
This article proposes a confidence interval based distributionally robust real-time economic dispatch (CI-DRED) approach, which considers the risk related to accommodating wind power. In this article, only the wind power curtailment and load shedding due

Effect of confidence interval construction on judgment accuracy [PDF]

open access: yesJudgment and Decision Making, 2020
Three experiments (N = 550) examined the effect of an interval construction elicitation method used in several expert elicitation studies on judgment accuracy.

Modified Clopper-Pearson Confidence Interval for Binomial Proportion [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2014
We introduce expected coverage probability as a measure for constructing confidence intervals for the binomial proportion, p. We propose a model based confidence interval for p using the expected coverage probabilities of the Clopper-Pearson interval ...
