Adaptive Robust Confidence Intervals [PDF]

open access: green
This paper studies the construction of adaptive confidence intervals under Huber's contamination model when the contamination proportion is unknown. For the robust confidence interval of a Gaussian mean, we show that the optimal length of an adaptive interval must be exponentially wider than that of a non-adaptive one.

Adaptively robust small area estimation: Balancing robustness and efficiency of empirical bayes confidence intervals [PDF]

open access: hybridScandinavian Journal of Statistics
ABSTRACTEmpirical Bayes (EB) small area estimation based on the well‐known Fay‐Herriot model may produce unreliable estimates when outlying areas exist. Existing robust methods against outliers or model misspecification are generally inefficient when the assumed distribution is plausible.

Robust Neighborhood Confidence Interval and Width to Evaluate the Outcome of a Binary Random Variable of Unequal Cluster Sizes

open access: diamondJournal of Biostatistics and Epidemiology
Bachground :While the main advantage of the confidence interval is that it enables more precise evaluations when the risk for the outcome of interest is related to the cluster size, the predicted confidence interval width demonstrates the degree of ...

ROBUSTNESS OF WILKS' CONSERVATIVE ESTIMATE OF CONFIDENCE INTERVALS [PDF]

open access: bronzeInternational Journal for Uncertainty Quantification, 2015
The striking generality and simplicity of Wilks’ method has made it popular for quantifying modeling uncertainty. A conservative estimate of the confidence interval is obtained from a very limited set of randomly drawn model sample values, with probability set by the assigned so-called stability. In contrast, the reproducibility of the estimated limits,

Model validation for a noninvasive arterial stenosis detection problem [PDF]

open access: yesMathematical Biosciences and Engineering, 2013
A current thrust in medical research is the development of a non-invasive method for detection, localization, and characterization of an arterial stenosis (a blockage or partial blockage in an artery).

Robust confidence intervals for meta-regression with interaction effects [PDF]

open access: hybridComputational Statistics
AbstractMeta-analysis is an important statistical technique for synthesizing the results of multiple studies regarding the same or closely related research question. So-called meta-regression extends meta-analysis models by accounting for study-level covariates.

Bootstrap Confidence Intervals for 11 Robust Correlations in the Presence of Outliers and Leverage Observations

open access: yesMethodology, 2022
Researchers often examine whether two continuous variables (X and Y) are linearly related. Pearson’s correlation (r) is a widely-employed statistic for assessing bivariate linearity.
