Hi, I am running the package as suggested, to get HC3 standard errors as such:
robust(mod1, 'hc3'), where mod1 is of "mfxlogit" class, and I get the following error:
Error in get(vcov_fun, asNamespace("sandwich")) : object 'vcovhc3' not found
I ran the same model a few days ago and it worked perfectly fine. I have also tried it with mod1 being of class "lm" or "glm".
Do you know what might be happening?
