margins with offset() in the model #188

Open mcfanda opened 1 year ago

mcfanda commented 1 year ago

It seems that the margins::margins command does not work well with glm models with offset() in the formula.

## load package

y<-rbinom(10,1,.5)
x<-rnorm(10,1,.5)
z<-rnorm(10,1,.5)
model<-glm(y~offset(z)+x,family=binomial())
margins::margins(model)
