Hello Gurus:
I'm using basic survival analysis, and trying to use survreg, and I provided
the parameter formula= and data=, but I got an error saying:
Error in terms.default(formula, special, data = data) : no terms
component
I'm wondering what it's trying to say. Is it because I didn't provide
"special"? I can't seem to find what that is in the documentation.
Thanks!
Karen
