Re: st: Hazard ratios to rates.

[Steven Samuels <sjhsamuels@earthlink.net>]

Hazard ratios compare two distributions, but you want to know  
something about one of the distributions.  It is the same as if you  
had asked: "I know the ratio of two numbers is 2:1.  What is one of  
them?"

So,unless you have more information, the answer to your question is  
"No".
