riskdiff

The riskdiff package provides robust methods for calculating risk differences (also known as prevalence differences in cross-sectional studies) using generalized linear models with automatic link function selection and boundary detection.

✨ Now Available on CRAN!

riskdiff v0.2.1 is now published on CRAN with cutting-edge boundary detection capabilities that identify when maximum likelihood estimates lie at the edge of the parameter space - a common issue with identity link models that other packages ignore.
