The risks package allows for fitting risk ratio and risk difference models using regression.
risks functions
riskratio: Fit risk ratio models.
riskdiff: Fit risk difference models.
summary.risks: Summarize fitted model.
tidy.risks: Tibble (data frame) of parameters,
coefficients, standard errors, confidence intervals.
confint.robpoisson,
confint.duplicate,
confint.margstd_boot,
confint.margstd_delta: Confidence intervals. (Standard
confidence intervals for generalized linear models are used for other
models.)
