A simple remedy for overprecision in judgment [PDF]
Judgment and Decision Making, 2010 Overprecision is the most robust type of overconfidence. We present a new method that significantly reduces this bias and offers insight into its underlying cause.

Do metabolic factors increase the risk of thyroid cancer? a Mendelian randomization study
Frontiers in Endocrinology, 2023 BackgroundEpidemiological studies emphasize the link between metabolic factors and thyroid cancer. Using Mendelian randomization (MR), we assessed the possible causal impact of metabolic factors on thyroid cancer for the first time.MethodsSummary ...

Brain magnetic resonance imaging predictors in anti‐N‐methyl‐D‐aspartate receptor encephalitis
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1974-1984, December 2022., 2022 Abstract Objective Brain magnetic resonance imaging (MRI) findings in anti‐N‐methyl‐D‐aspartate receptor (NMDAR) encephalitis are nonspecific and rarely have obvious associations with clinical characteristics and outcomes. This study aimed to comprehensively describe the MRI features of patients with NMDAR encephalitis, examine their associations with ...

A Conditional-Heteroskedasticity-Robust Confidence Interval for the Autoregressive Parameter [PDF]
Review of Economics and Statistics, 2011 This paper introduces a new confidence interval (CI) for the autoregressive parameter (AR) in an AR(1) model that allows for conditional heteroskedasticity of general form and AR parameters that are less than or equal to unity. The CI is a modification of Mikusheva's (2007a) modification of Stock's (1991) CI that employs the least squares estimator and

Robust Confidence Intervals for Average Treatment Effects Under Limited Overlap
Social Science Research Network, 2017 Estimators of average treatment effects under unconfounded treatment assignment are known to become rather imprecise if there is limited overlap in the covariate distributions between the treatment groups.

Confidence interval based parameter estimation--a new SOCR applet and activity. [PDF]
PLoS ONE, 2011 Many scientific investigations depend on obtaining data-driven, accurate, robust and computationally-tractable parameter estimates. In the face of unavoidable intrinsic variability, there are different algorithmic approaches, prior assumptions and ...

Use of the bootstrap in analysing cost data from cluster randomised trials: some simulation results
BMC Health Services Research, 2004 Background This work has investigated under what conditions confidence intervals around the differences in mean costs from a cluster RCT are suitable for estimation using a commonly used cluster-adjusted bootstrap in preference to methods that utilise ...

Which Robust Regression Technique Is Appropriate Under Violated Assumptions? A Simulation Study
Methodology, 2023 Ordinary least squares (OLS) regression is widely employed for statistical prediction and theoretical explanation in psychology studies. However, OLS regression has a critical drawback: it becomes less accurate in the presence of outliers and non-random ...
