%description
Calculates risk differences (or prevalence differences for cross-sectional
data) using generalized linear models with automatic link function
selection. Provides robust model fitting with fallback methods, support
for stratification and adjustment variables, inverse probability of
treatment weighting (IPTW) for causal inference, and publication-ready
output formatting. Handles model convergence issues gracefully and
provides confidence intervals using multiple approaches. Methods are based
on approaches described in Mark W. Donoghoe and Ian C. Marschner (2018)

Model" <doi:10.18637/jss.v086.i09> for robust GLM fitting, Peter C. Austin

Effects of Confounding in Observational Studies"
