Using Robust Standard Errors to Combine Multiple Regression Estimates with Meta-Analysis
… purpose of this study was to explore the use of robust variance estimation for combining commonly specified multiple regression models and for combining sample-dependent focal slope estimates from diversely specified models. A series of Monte-Carlo simulations were conducted to investigate the …

The Influence of Task Process and Task Structure on Transactive Memory Systems and Team Outcomes: A Meta-Regression Analysis
… positive effects for all team outcomes through a robust variance estimation, <em>z </em>= 0.47 (<em>r</em> = 0.44), 95% CI [0.38, 0.56], p < .001. Exploratory meta-regression results revealed a significant difference in outcome measurement type, with self-report surveys (<em>z </em>= 0.78, r = …

Power approximation for the test of study-level categorical moderators in meta-regression with dependent effect sizes
… the correlated-hierarchical effects model with robust variance estimation (CHE+RVE). Additionally, I conduct a Monte Carlo simulation to validate this power approximation formula against the true simulated power of a test of multiple contrasts from a CHE+RVE model. I also examine the Type I …

WELL-BEING AND NEGATIVE MOOD OF SOUTH ASIAN AMERICAN COLLEGE STUDENTS: CONTRIBUTIONS OF ADULT ATTACHMENT, ACCULTURATION, AND RACIAL IDENTITY
… acculturation and racial identity account for robust variance in the prediction of self-esteem, anxious mood, and depressed mood. Adult attachment, acculturation and racial identity accounted for variance in self-esteem, and more specifically, avoidant attachment, anxious attachment, and racial …

Impacto da estratégia saúde da família com equipe de saúde bucal sobre indicadores de saúde bucal: análise em municípios do nordeste com mais de 100 mil habitantes
… factors through Poisson regression with robust variance. It also has measured the association between an indicator of social inequality for comparison between areas. The best results are associated with indicators of access and coverage of oral health actions at the expense of the …

Qualidade do sono, sonolência diurna e fatores associados em estudantes universitários: um estudo baseado nos determinantes sociais
… daytime sleepiness, Poisson regression with robust variance was used, in which the prevalence ratios (PR) were estimated in the bivariate and multivariate analysis. In the intermediate model, variables that had a value of p <0.20, obtained in the bivariate analysis, were initially considered, …

Weighting and moment conditions in Bayesian inference
… use estimated weights include so-called doubly robust estimators, which have become popular in causal inference. There is a lack of consensus regarding the role of probability weights in Bayesian inference. In some settings, it is reasonable to believe that conditioning on certain observed …

Ambulatory and hospitalized childhood pneumonia: a longitudinal study in a peri-urban low-income community with high vaccination coverage in Sub-Saharan Africa
… ratios from modified Poisson regression with robust variance estimation. Findings From March 2012 to March 2015, 1137 pregnant women were enrolled, delivering 1143 live-born infants. Household environmental tobacco smoke exposure was common: 82% of children were exposed in the first 6 months …
