Confidence interval how sure you are?

open access: yesJournal of Applied Hematology, 2014
Previously, researchers were reported P value as a basis for conclusion, but in this era of evidence-based medicine we are interested now about the precision of the results obtained that allow us to make right decisions in health care practice.

A New Exact Confidence Interval for the Difference of Two Binomial Proportions

open access: yesRevstat Statistical Journal, 2020
We consider interval estimation of the difference between two binomial proportions. Several methds of constructing such an interval are known. Unfortunately those confidence intervals have poor coverage probability: it is significantly smaller than the ...

A second-order efficient empirical Bayes confidence interval [PDF]

open access: yes, 2014
We introduce a new adjusted residual maximum likelihood method (REML) in the context of producing an empirical Bayes (EB) confidence interval for a normal mean, a problem of great interest in different small area applications.

The Shortest Clopper–Pearson Randomized Confidence Interval for Binomial Probability

open access: yesRevstat Statistical Journal, 2017
Zieli´nski (2010) showed the existence of the shortest Clopper–Pearson confidence interval for binomial probability. The method of obtaining such an interval was presented as well. Unfortunately, the confidence interval obtained has one disadvantage: it

Multivariate Confidence Intervals [PDF]

open access: yes, 2017
Confidence intervals are a popular way to visualize and analyze data distributions. Unlike p-values, they can convey information both about statistical significance as well as effect size. However, very little work exists on applying confidence intervals to multivariate data.

Interval-Valued Intuitionistic Fuzzy Confidence Intervals

open access: yesJournal of Intelligent Systems, 2019
Confidence intervals are useful tools for statistical decision-making purposes. In case of incomplete and vague data, fuzzy confidence intervals can be used for decision making under uncertainty.

Confidence interval estimation for standardized effect sizes in multilevel and latent growth modeling.

open access: yesJournal of Consulting and Clinical Psychology, 2015
OBJECTIVE Multilevel and latent growth models are frequently used interchangeably to examine differences between groups in trajectories of outcomes from controlled clinical trials.

Comparison of confidence interval methods for an intra-class correlation coefficient (ICC)

open access: yesBMC Medical Research Methodology, 2014
BackgroundThe intraclass correlation coefficient (ICC) is widely used in biomedical research to assess the reproducibility of measurements between raters, labs, technicians, or devices.

Fixed-width confidence interval for a lognormal mean

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We consider the problem of constructing a fixed-width confidence interval for a lognormal mean. We give a Birnbaum and Healy type two-stage procedure to construct such a confidence interval. We discuss some asymptotic properties of the procedure. A three-

Comparison of the Frequentist MATA Confidence Interval with Bayesian Model-Averaged Confidence Intervals

open access: yesJournal of Probability and Statistics, 2015
Model averaging is a technique used to account for model uncertainty, in both Bayesian and frequentist multimodel inferences. In this paper, we compare the performance of model-averaged Bayesian credible intervals and frequentist confidence intervals ...
