%description
Provides a suite of helper functions to support Bayesian Kernel Machine
Regression (BKMR) analyses in environmental health research. It enables
the simulation of realistic multivariate exposure data using Multivariate
Skewed Gamma distributions, estimation of distributional parameters by
subgroup, and application of adaptive, data-driven thresholds for feature
selection via Posterior Inclusion Probabilities (PIPs). It is especially
suited for handling skewed exposure data and enhancing the
interpretability of BKMR results through principled variable selection.
The methodology is shown in Hasan et. al. (2025)
<doi:10.1101/2025.04.14.25325822>.
