There is not a mechanism to get the internal bits of survreg. This is
unlike coxph, where I wrote the coxph.detail routine to give exactly what
you ask (for debugging purposes). It has turned out to be very useful.
However, the source code for survreg is available, look at the survival
package on our department's web site www.mayo.edu/biostatistics
(Insightful decided to put a capital letter into the middle of "survreg",
beyond that it is the code from Mayo). You could certainly add print
statements into the C code.

Hi,
With survReg, it is possible to get the inverse Hessian:
> fit_survReg(...)
> fit$var
Is it possible to get also the score matrix? More generally, how can I
get all the steps of the procedure? A sort of debugging for survReg
(SPlus 7)...
Thanks,
Tristan Lorino
