Assessing the similarity of dose response and target doses in two non-overlapping subgroups [PDF]

open access: yes, 2017
We consider two problems that are attracting increasing attention in clinical dose finding studies. First, we assess the similarity of two non-linear regression models for two non-overlapping subgroups of patients over a restricted covariate space.

Fixed-width confidence interval for a lognormal mean

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We consider the problem of constructing a fixed-width confidence interval for a lognormal mean. We give a Birnbaum and Healy type two-stage procedure to construct such a confidence interval. We discuss some asymptotic properties of the procedure. A three-

Comment on "Including Systematic Uncertainties in Confidence Interval Construction for Poisson Statistics" [PDF]

open access: yes, 2003
The incorporation of systematic uncertainties into confidence interval calculations has been addressed recently in a paper by Conrad et al. (Physical Review D 67 (2003) 012002).

Mortality among Lifelong Nonsmokers Exposed to Secondhand Smoke at Home: Cohort Data and Sensitivity Analyses [PDF]

open access: yes, 2006
Evidence is growing that secondhand smoke can cause death from several diseases. The association between household exposure to secondhand smoke and disease-specific mortality was examined in two New Zealand cohorts of lifelong nonsmokers (‘‘never smokers’

Comparison of the Frequentist MATA Confidence Interval with Bayesian Model-Averaged Confidence Intervals

open access: yesJournal of Probability and Statistics, 2015
Model averaging is a technique used to account for model uncertainty, in both Bayesian and frequentist multimodel inferences. In this paper, we compare the performance of model-averaged Bayesian credible intervals and frequentist confidence intervals ...

Pragmatism should Not be a Substitute for Statistical Literacy, a Commentary on Albers, Kiers, and Van Ravenzwaaij (2018)

open access: yesCollabra: Psychology, 2019
Based on the observation that frequentist confidence intervals and Bayesian credible intervals sometimes happen to have the same numerical boundaries (under very specific conditions), Albers et al.

Confidence Interval for Quantile Ratio of the Dagum Distribution

open access: yesRevstat Statistical Journal, 2021
Inequality measures based on ratios of quantiles are frequently applied in economic research, especially to the analysis of income distributions. In the paper, we construct a confidence interval for such measures under the Dagum distribution which has ...

Alendronate or alfacalcidol in glucocorticoid-induced osteoporosis [PDF]

open access: yes, 2006
BACKGROUND: Treatment with glucocorticoids is associated with bone loss starting soon after therapy is initiated and an increased risk of fracture. METHODS: We performed a randomized, double-placebo, double-blind clinical trial of 18 months' duration ...

Fractal dimension confidence interval estimation of epicentral distributions

open access: yesAnnals of Geophysics, 1999
Estimates of the fractal dimension of hypocentral distributions require evaluating the range of independent variables in which fractal parameters exhibit a power law.

Improving Point and Interval Estimates of Monotone Functions by Rearrangement [PDF]

open access: yes, 2008
Suppose that a target function is monotonic, namely, weakly increasing, and an available original estimate of this target function is not weakly increasing.
