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

Wind Power Interval Forecasting Based on Confidence Interval Optimization

open access: yesEnergies, 2018
Most of the current wind power interval forecast methods are based on the assumption the point forecast error is subject to a known distribution (such as a normal distribution, beta distribution, etc.).

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 fallacy of placing confidence in confidence intervals [PDF]

open access: yesPsychonomic Bulletin & Review, 2015
Interval estimates - estimates of parameters that include an allowance for sampling uncertainty - have long been touted as a key component of statistical analyses. There are several kinds of interval estimates, but the most popular are confidence intervals (CIs): intervals that contain the true parameter value in some known proportion of repeated ...

Sample size estimation for correlations with pre-specified confidence interval [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2014
A common measure of association between two variables x and y is the bivariate Pearson correlation coefficient rho(x,y) that characterizes the strength and direction of any linear relationship between x and y.

On construction of the smallest one-sided confidence interval for the difference of two proportions [PDF]

open access: yes, 2010
For any class of one-sided $1-\alpha$ confidence intervals with a certain monotonicity ordering on the random confidence limit, the smallest interval, in the sense of the set inclusion for the difference of two proportions of two independent binomial ...

Confidence with confidence intervals

open access: yesIndian Journal of Ophthalmology, 1997
When considering the results of a study that reports one treatment to be better than another, what the practicing ophthalmologist really wants to know is the magnitude of the difference between treatment groups. If this difference is large enough, we may

Measurement of dispersion of PM 2.5 in Thailand using confidence intervals for the coefficient of variation of an inverse Gaussian distribution [PDF]

open access: yesPeerJ, 2022
Air pollution is a growing concern for the general public in Thailand with PM 2.5 (particulate matter ≤ 2.5 µm) having the greatest impact on health. The inverse Gaussian (IG) distribution is used for examining the frequency of high concentration events ...
