st: interpreting time ratios in survival analysis

["Bodenhorn, Howard N" <bodenhoh@lafayette.edu>]

In -streg, an option is -tr, which reports time ratios rather than 
coefficients for survival models. My question is about the interpretation of a 
time ratio. If the estimated time ratio equals, say, 0.88, how am I to 
interpret that result? How do I interpret it for a continuous varaible and for 
a dummy variable? Thanks.
