Understanding and interpreting confidence and credible intervals around effect estimates.
Brazilian Journal of Physical Therapy, 2019 INTRODUCTION Reporting confidence intervals in scientific articles is important and relevant for evidence-based practice. Clinicians should understand confidence intervals in order to determine if they can realistically expect results similar to those ...

Markov Chain Monte Carlo confidence intervals
, 2016 For a reversible and ergodic Markov chain $\{X_n,n\geq0\}$ with invariant distribution $\pi$, we show that a valid confidence interval for $\pi(h)$ can be constructed whenever the asymptotic variance $\sigma^2_P(h)$ is finite and positive.

Correlation Coefficients: Mean Bias and Confidence Interval Distortions
Journal of Methods and Measurement in the Social Sciences, 2011 Non-zero correlation coefficients have non-normal distributions, affecting both means and standard deviations. Previous research suggests that z transformation may effectively correct mean bias for N's less than 30. In this study, simulations with small (

A review of effect sizes and their confidence intervals, Part I: The Cohen's d family
The Quantitative Methods for Psychology, 2018 The results of the interval estimation method popularized by Steiger and Fouladi (1997), herein called the pivoting method1, were displayed erroneously in Appendix C of our recent paper on effect sizes and corresponding confidence intervals (Goulet ...

P-value, compatibility, and S-value
Global Epidemiology, 2022 Misinterpretations of P-values and 95% confidence intervals are ubiquitous in medical research. Specifically, the terms significance or confidence, extensively used in medical papers, ignore biases and violations of statistical assumptions and hence ...

Confidence Interval Estimation of Proportion Near Zero or One: A Modeling Secondary Study
مجله اپیدمیولوژی ایران, 2017 Background and Objectives: When computing a confidence interval for a binomial proportion p, one must choose an exact interval that has a coverage probability of at least 1-α for all values of p.
