Better Confidence Intervals for a Binomial Proportion

open access: yesCommunications, 2010
Interval estimation of a binomial proportion is one of the basic problems in statistics. In technical practice a binomial proportion is often used in statistical quality control.

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.

Calculating confidence intervals for impact numbers

open access: yesBMC Medical Research Methodology, 2006

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,

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

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.

Confidence Intervals: From tests of statistical significance to confidence intervals, range hypotheses and substantial effects [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2006
For the last 50 years of research in quantitative social sciences, the empirical evaluation of scientific hypotheses has been based on the rejection or not of the null hypothesis.

Calculating unreported confidence intervals for paired data

open access: yesBMC Medical Research Methodology, 2011
Background Confidence intervals (or associated standard errors) facilitate assessment of the practical importance of the findings of a health study, and their incorporation into a meta-analysis.

An extension of within-subject confidence intervals to models with crossed random effects [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2017
A common problem in displaying within-subject data is that of how to show confidence intervals that accurately reflect the pattern of significant differences between conditions. The Cousineau-Morey method \parencite {c05,m08} is a widely used solution to
