%description
Implements a permutation test method for the weighted quantile sum (WQS)
regression, building off the 'gWQS' package (Renzetti et al. (2021)
<https://CRAN.R-project.org/package=gWQS>). Weighted quantile sum
regression is a statistical technique to evaluate the effect of complex
exposure mixtures on an outcome (Carrico et al. (2015)
<doi:10.1007/s13253-014-0180-3>). The model features a statistical power
and Type I error (i.e., false positive) rate trade-off, as there is a
machine learning step to determine the weights that optimize the linear
model fit. This package provides an alternative method based on a
permutation test that should reliably allow for both high power and low
false positive rate when utilizing WQS regression (Day et al. (2022)
<doi:10.1289/EHP10570>).
