Are you sure about that? It seems to me it isn't (or I am doing
something terribly wrong). -dfbeta- and -predict- with option
dfbeta(varname) generate 'last estimates not found' and 'option dfbeta()
not allowed' accordingly. -est- confirmed that the estimates from
-streg- were indeed present. I tried them both after -regress- and they
seemed to work fine.
Options leverage and cooksd don't seem to be supported after streg
either. 

Are there any other ways to perform such an analysis in stata or am I
out of luck? I am using stata 9.

I think that this is a new enhancement to Stata 9.
-dfbeta- now works for survival data just like for
-regress-.

I guess is time to upgrade.
