THE PHYSICAL SIGNIFICANCE OF CONFIDENCE INTERVALS [PDF]

open access: yesInternational Journal of Modern Physics C, 2001
We define some appropriate statistical quantities that indicate the physical significance (reliability) of confidence intervals in the framework of both Frequentist and Bayesian statistical theories. We consider the expectation value of the upper limit in the absence of a signal (that we propose to call "exclusion potential", instead of "sensitivity ...

A calculator for confidence intervals [PDF]

open access: yesComputer Physics Communications, 2002
A calculator program has been written to give confidence intervals on branching ratios for rare decay modes (or similar quantities) calculated from the number of events observed, the acceptance factor, the background estimate and the associated errors.

Comparison of confidence intervals for fraction in finite populations

open access: yesQuantitative Methods in Economics, 2011
Consider a finite population. Let θ ∈(0,1) denotes the fraction of units with a given property. The problem is in interval estimation of θ on the basis of a sample drawn due to the simple random sampling without replacement. In the paper three confidence

Correlation Coefficients: Mean Bias and Confidence Interval Distortions

open access: yesJournal 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 (

Confidence Interval Estimation of Proportion Near Zero or One: A Modeling Secondary Study

open access: yesمجله 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.

Alternatives to P value: confidence interval and effect size [PDF]

open access: yesKorean Journal of Anesthesiology, 2016
The previous articles of the Statistical Round in the Korean Journal of Anesthesiology posed a strong enquiry on the issue of null hypothesis significance testing (NHST).

P-value, compatibility, and S-value

open access: yesGlobal 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 ...

Simultaneous Confidence Intervals for Pairwise Differences of Means in Zero-Inflated Rayleigh Distributions with an Application to Road Accident Fatalities Data

open access: yesMathematics
This paper develops simultaneous confidence intervals (SCIs) for pairwise differences of means with zero-inflated Rayleigh (ZIR) distributions, a flexible framework for modeling positively skewed data with excess zeros.

The P value and statistical significance: Misunderstandings, explanations, challenges, and alternatives

open access: yesIndian Journal of Psychological Medicine, 2019
The calculation of a P value in research and especially the use of a threshold to declare the statistical significance of the P value have both been challenged in recent years.

Common pitfalls in statistical analysis: "P" values, statistical significance and confidence intervals

open access: yesPerspectives in Clinical Research, 2015
In the second part of a series on pitfalls in statistical analysis, we look at various ways in which a statistically significant study result can be expressed.
