homogeneity_test.qgcompmultfit

Tests the null hypothesis that the joint effect of the mixture components is identical across all referent outcome types (homogeneity test for linear effect of the mixture on a quantized basis)

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.
