Reward predictions bias attentional selection
Frontiers in Human Neuroscience, 2013 Attention selects stimuli for perceptual and cognitive processing according to an adaptive selection schedule. It has long been known that attention selects stimuli that are task relevant or perceptually salient.

Variable Selection Bias in Classification Trees Based on Imprecise Probabilities [PDF]
, 2005 Classification trees based on imprecise probabilities provide an advancement of classical classification trees. The Gini Index is the default splitting criterion in classical classification trees, while in classification trees based on imprecise ...

Credible Mendelian Randomization Studies in the Presence of Selection Bias Using Control Exposures
Frontiers in Genetics, 2021 Selection bias is increasingly acknowledged as a limitation of Mendelian randomization (MR). However, few methods exist to assess this issue. We focus on two plausible causal structures relevant to MR studies and illustrate the data-generating process ...

Statistical Sources of Variable Selection Bias in Classification Tree Algorithms Based on the Gini Index [PDF]
, 2005 Evidence for variable selection bias in classification tree algorithms based on the Gini Index is reviewed from the literature and embedded into a broader explanatory scheme: Variable selection bias in classification tree algorithms based on the Gini ...

Scientific Research or Advocacy? Emotive Labels and Selection Bias Confound Survey Results
Ecology and Society, 2000 Robert Costanza presents four compelling visions of the future, but the language he uses to describe them is emotive and value-laden and may bias the survey results.

Selection Bias, Confounding, or Information Bias? [PDF]
Hypertension, 2007 To the Editor, As a public health advocate against tobacco use, I find the recent article by Jatoi et al1 interesting and quite informative. As an epidemiologist, I also have a few concerns surrounding the methodologic issues of such study findings. One of the most essential components of a comprehensive tobacco control program is to disseminate the ...

Accounting for biases in survey-based estimates of population attributable fractions
Population Health Metrics, 2019 Background This paper discusses best practices for estimating fractions of mortality attributable to health exposures in survey data that are biased by observed confounders and unobserved endogenous selection.

Optimal classifier selection and negative bias in error rate estimation: An empirical study on high-dimensional prediction [PDF]
, 2009 In biometric practice, researchers often apply a large number of different methods in a "trial-and-error" strategy to get as much as possible out of their data and, due to publication pressure or pressure from the consulting customer, present only the ...
