[R] survreg's algorithm

[Gad Abraham]

Hi,

I'm using survreg() from the survival package for parametric survival 
regression (modelling inter-arrival times of patients to a waiting list 
as exponentially distributed, with various regressors such as queue size 
and season).

Does anyone know which algorithm survreg() uses for this?

Thanks,
Gad
