WebExample using the bkmr R package for probit regression with simulated data. WebThe Bayesian kernel machine regression (BKMR) model, which provides for a more flexible assessment of the combined consequences of numerous pollutants while identifying potential interactions and... BKMR can be extended to binary outcomes via generalized linear modeling. For reasons of computational efficiency for Bayesian inference, we use probit, rather than logistic, regression. The probit BKMR model is given by where Φ is the cumulative distribution function (CDF) for the standard normal … See more We first provide a brief overview of BKMR. The kernel machine regression (KMR) model for a continuous outcome is given by where Yi denotes the response for individual i (i = 1, …, n), zim is the mth exposure variable, h … See more From fitting the BKMR model, one obtains an estimate of the exposure-response function h, which may include nonlinear and non-additive associations. Unless there are very few mixture components, it is not possible to … See more The bkmr software is implemented as an R (R Development Core Team 2024) package. It has dependencies to the following packages: … See more A major computational burden in fitting BKMR is the need to invert an n-by-n matrix (multiple times) at each iteration of the algorithm, where n is equal to the number of observations in the data.
