A justification of conditional confidence intervals [PDF]

open access: yesElectronic Journal of Statistics, 2021
To quantify uncertainty around point estimates of conditional objects such as conditional means or variances, parameter uncertainty has to be taken into account. Attempts to incorporate parameter uncertainty are typically based on the unrealistic assumption of observing two independent processes, where one is used for parameter estimation, and the ...

Significant results: statistical or clinical? [PDF]

open access: yesKorean Journal of Anesthesiology, 2016
The null hypothesis significance test method is popular in biological and medical research. Many researchers have used this method for their research without exact knowledge, though it has both merits and shortcomings. Readers will know its shortcomings,

A review of effect sizes and their confidence intervals, Part I: The Cohen's d family

open access: yesThe 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 ...

Better Bootstrap Confidence Intervals

open access: yes, 1987
We consider the problem of setting approximate confidence intervals for a single parameter θ in a multiparameter family. The standard approximate intervals based on maximum likelihood theory, , can be quite misleading.

L'établissement d'une norme de qualification sûre dans un contexte non paramétrique [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2008
La sélection de personnel pour un emploi se base souvent sur une norme psychométrique qu’un candidat doit atteindre afin d’être recruté. Or, cette norme est statistique, c’est-à-dire calculée sur les mesures d’un simple échantillon de la population ...

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.

A note on confidence intervals for deblurred images [PDF]

open access: yesOpuscula Mathematica, 2020
We consider pointwise asymptotic confidence intervals for images that are blurred and observed in additive white noise. This amounts to solving a stochastic inverse problem with a convolution operator.

Using the confidence interval confidently [PDF]

open access: yesJournal of Thoracic Disease, 2017
Biomedical research is seldom done with entire populations but rather with samples drawn from a population. Although we work with samples, our goal is to describe and draw inferences regarding the underlying population. It is possible to use a sample statistic and estimates of error in the sample to get a fair idea of the population parameter, not as a

Generating confidence intervals on biological networks

open access: yesBMC Bioinformatics, 2007
Background In the analysis of networks we frequently require the statistical significance of some network statistic, such as measures of similarity for the properties of interacting nodes. The structure of the network may introduce dependencies among the

Correlation-adjusted standard errors and confidence intervals for within-subject designs: A simple multiplicative approach [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2019
In within-subject designs, the multiple scores of a given participant are correlated. This correlation implies that the observed variance can be partitioned into between-subject variance and between-measure variance.
