R help - Mar 2006 - duration analysis

Hi,

I am trying to estimate the effects of covariates on the hazard function, rather
than on the survival. I know this is actually the same thing. For example, using
the survival package, and doing:
> myfit <- survreg( Surv(time, event) ~ mymodel )
all I have to do to get the quantities of my interest is
> -myfit$coefficients/myfit$scale
The standard erros are easily worked out, as the absolute z-statistics are the
same.

Ok, so I can get easily what I want from survreg(). But I'd like to get it
even
more directly. Does anyone know some function to do it?

Thank you,
Dimitri Szerman
