st: survival analysis: an elementary question

[Michael McCulloch <mm@pinest.org>]

Hello,
Is it theoretically possible for the 95% confidence interval about 
the hazard ratio to include 0, such that the lower bound is a 
negative number? I've encountered into this with a program I've 
written (too long to post here, and I don't want to bother anyone), 
but I'm certain I've done something incorrectly. Might someone have a 
moment to clarify this question?
