This calculator will compute the total effect of a mediation model, given the regression coefficient between the independent variable and the mediator variable, the regression coefficient between the mediator variable and the dependent variable, and the regression coefficient between the independent variable...
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...
Two-level moderated mediation models with single-level data and new measures of effect sizes 来自 NCBI 喜欢 0 阅读量: 100 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 the ...
Full size image Fig. 6 Mulberry Plot of GM and circulating inflammatory proteins. Full size image Discussion Prior investigations have validated the influence of the intestinal microbiome on the overall well-being of humans. Indeed, intestinal microbiome not only mediates interactions between gut commens...
Full size table Fig. 2 Path diagram of the association between solid cooking fuel use and psychological distress with sleep quality as a mediator. Notes: ** p < 0.05, *** p < 0.001. 95% CIs in the parentheses are shown. Models control for age, gender, education, marriage stat...
Full size table Fig. 2 Quantile-quantile plots of p-values from different global mediation tests in the simulation study for the continuous outcome. The observed p-values were compared to the expected quantiles generated by the uniform null distribution. The [Math Processing Error]|Sα| and [Ma...
Mediation analysis is routinely adopted by researchers from a wide range of applied disciplines as a statistical tool to disentangle the causal pathways by which an exposure or treatment affects an outcome. The counterfactual framework provides a language for clearly defining path-specific effects of in...
Mediation analysis may explain the causal effect on satisfaction with life. We expect that self-efficacy will mediate the relationships between health locus of control and satisfaction with life, and this association will be moderated by acquired movement disability. In the mediated moderation model, ...
Full size image The neocortical and cerebellar regions are thought to constitute functional-anatomical loops, specifically involving the cerebellar and pontine nuclei and basal ganglia41,44,51. Anatomically, the loop topology has been identified not only between sensorimotor neocortical and ventromedial cer...
mediation, indirect effect, effect sizeThe statistical analysis of mediation effects has become an indispensable tool for helping scientists investigate processes thought to be causal. Yet, in spite of many recent advances in the estimation and testing of mediation effects, little attention has been ...
