Web28 de ago. de 2024 · BKMR can perform either component-wise or hierarchical variable selection. Here, we employed hierarchical variable selection, which provides group importance scores (Posterior Inclusion Probabilities, PIPs) for pre-defined mutually-exclusive groups of variables, in addition to estimating the importance of a congener given that the … Web1 de fev. de 2024 · BKMR can identify nonlinear and non-additive relationships within chemicals. Because the chemicals in our analysis were highly correlated, we conducted a hierarchical variable selection method with 50,000 iterations by a Markov chain Monte Carlo algorithm.

Web1 de set. de 2024 · Another recent study using BKMR suggested a potential joint effect between As and Mn on birth weight [29]. In the present study, we used a lasso for hierarchical interactions to estimate the combined effect of exposure to metal mixtures during pregnancy on birth weight [36]. WebWe first developed a BKMR variable-selection approach, which we call component-wise variable selection, to make estimating such a potentially complex exposure-response … rcgp study leave west midlands
