WebIntroduction to Bayesian kernel machine regression and the bkmr R package. WebMar 7, 2024 · Linear regression models were used to explore the relationship between different dietary patterns and depressive symptoms of men and women. We used weighted quantile sum (WQS) regression, quantile g calculation (qgcomp) and Bayesian kernel machine regression (BKMR) as the secondary analysis. Exposure and Outcome Variables

WebWe would like to show you a description here but the site won’t allow us. WebAug 16, 2024 · BKMR is a semi-parametric approach for estimating the effects of individual mixture components, global mixture effects, and mixture component interactions (Bobb et al. 2015). A probabilistic link function was used to fit exposure–response connections for binary outcomes.
WebUltimately, BKMR modeling is a technique that (1) models the exposures and outcomes comprehensively, (2) evaluates the components of chemicals independently of the independent–dependent function, (3) evaluates the effects of mixtures of chemicals, and (4) distinguishes the necessary chemical mixtures for any dataset that is simulated [19,21]. WebMay 6, 2024 · where Φ −1 was the link function and μ i represented the probability of the dichotomous outcome, Z i represented covariates while β served as their coefficients. h could be construed as the relationship between exposure and a latent continuous outcome. The outputs of BKMR could interpret the overall OPEs metabolites effects when all the …
WebMar 16, 2024 · The BKMR framework is a flexible nonparametric approach that allows the estimation of the overall effect estimate of multiple correlated exposures accounting for confounding variables. 49 The method was implemented with the R package “bkmr” using 10,000 iterations. 50 All variables were included in the model using the variable selection …
