Assessing publication bias in coordinate-based meta-analysis techniques?

Publication Bias in Meta-Analysis

Publication bias is the term for what occurs whenever the research that appears in the published literature is systematically unrepresentative of the population of completed studies. Simply put, when the research that is readily available differs in its results from the results of all the research that has been done in an area, readers and reviewers of that research are in danger of drawing the...

Adjusting for Publication Bias in Meta-Analysis

We review and evaluate selection methods, a prominent class of techniques first proposed by Hedges (1984) that assess and adjust for publication bias in meta-analysis, via an extensive simulation study. Our simulation covers both restrictive settings as well as more realistic settings and proceeds across multiple metrics that assess different aspects of model performance. This evaluation is tim...

Assessing publication bias in genetic association studies: evidence from a recent meta-analysis.

Publication bias may exist when nonsignificant findings remain unpublished, thereby artificially inflating the apparent magnitude of an effect. This concern is not new, but it is particularly current in relation to genetic association studies. Data from a recent meta-analysis of association studies of personality were used to assess the potential of different graphical and statistical methods f...

A Non-parametric \Trim and Fill" Method of Assessing Publication Bias in Meta-analysis

Meta-analysis collects and synthesizes results from individual studies to estimate an overall eeect size. If published studies are chosen, say through a literature review, an inherent selection bias may arise, since for example, studies may tend to be published more readily if they are statistically signiicant, or deemed to be morèinteresting' in terms of the impact of their outcomes. We develo...
