This R package runs flexible mediation analyses using natural effect models, as introduced in Lange, T., Vansteelandt, S., & Bekaert, M. (2012). A Simple Unified Approach for Estimating Natural Direct and Indirect Effects.American Journal of Epidemiology,176(3), 190-195.doi:10.1093/aje/kw...
Effect size measures for mediation models: quantitative strategies for communicating indirect effects. The statistical analysis of mediation effects has become an indispensable tool for helping scientists investigate processes thought to be causal. Yet, in s...

Two-level moderated mediation models with single-level data and new measures of effect sizes 来自 Semantic Scholar 喜欢 0 阅读量: 111 作者:H Liu,KH Yuan,Z Wen 摘要: This article proposes a two-level moderated mediation (2moME) model with single level data, and develops measures to quantify...
Full size image 3.2 Hypotheses development Smartphones, with their superior portability and personal affinity, have revolutionized our daily lives, becoming an integral part of our routines [50]. The affinity toward such technology significantly contributes to SAT. For instance, Xu and Du’s [61] ...
However, the effect of BMI between TypeIII and HbA1c was small, accounting for about 1.22%, and our mediation analysis found that the media- tion effect was also close to the critical value, which may be limited by our sample size and study population. Advantages of the research First...

Full size image Moderation analysis of the role of ER in the relationship between stress and cognition Finally, we tested whether ER moderates the impact of stress on cognition (Fig.3, Supplementary TableT6). In women, we found only one moderating and few direct effects associated mainly with ...
Full size image 4 Research methodology We conducted an exploratory, descriptive, and inferential study to achieve our research objectives and answer the questions raised. The methods included statistical correlations and regression models. 4.1 Description of sample We chose to conduct this study in the...
Full size image We develop a testing procedure to ensure the PhyloMed local mediation testp-values are asymptotically mutually independent and uniformly distributed under the global null hypothesis that no mediation effect in any of the internal nodes (Methods). We apply a FDR-controlling procedure ...
