page 343,344 are for random censoring. I'm not sure (or am doubtful that this applies with identical censoring by a fixed limit.)

What happens with Kaplan-Meier when everybody is censored at the same point ?

@gpanterov  Did you use another reference for censored regression, or is it based on the different parts of books and papers by Li, Racine?
Except for browsing these pages in the book, I haven't looked at any of these, so I'm still trying to figure out what's going on.
