%description
G-computation for a set of time-fixed exposures with quantile-based basis
functions, possibly under linearity and homogeneity assumptions. This
approach estimates a regression line corresponding to the expected change
in the outcome (on the link basis) given a simultaneous increase in the
quantile-based category for all exposures. Works with continuous, binary,
and right-censored time-to-event outcomes.  Reference: Alexander P. Keil,
Jessie P. Buckley, Katie M. OBrien, Kelly K. Ferguson, Shanshan Zhao, and
Alexandra J. White (2019) A quantile-based g-computation approach to
addressing the effects of exposure mixtures; <doi:10.1289/EHP5838>.
