Bkmr for binary outcome
WebRESULTS Applying the methods to a continuous outcome example illustrated the ability of the BKMR implementation to estimate the health effects of multi-pollutant mixtures in the context of a highly nonlinear, biologically-based dose-response function, and to estimate overall, single-exposure, and interactive health effects. 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 …
