risk ratio and risk difference

[MikeJSeo]

How to estimate risk ratio/risk difference? I did a quick search.

risk ratio: looks like log link doesn't work? i.e. family = binomial(link = "log))
instead uses poisson with log link and find standard error via sandwich package/bootstrap

risk difference: looks like you fit a regular logistic regression with logit link, predict the probabilities and subtract them.. standard error is found by bootstrap

Alternate way to calculate is maybe via using marginaleffects library

There seems to be even a R package called risks that does this..
