Dear Rose,
just to top off Maarten's and Martin's superb advices on this topic, you can
find some stuff on pseudo-random number generating idea in:
- Juul S. An Introduction to Stata for Health Researchers. College Station:
Stata Press, 2006: 257;
- Davidson R, MacKinnon JG. Econometric Theory and Methods. Oxford:Oxford
University Press, 2004: 18; 157-159.
Kind Regards,
Carlo

Oggetto: st: how to cancel the seed set previously?
I set seed # before the runiform() function.
For instance,
I typed,
set seed 100
g x=runinform()
my confusions are,
1.how to set the seed number propriately? I saw everyone set it large.Any
difference?
2. how to cancel the seed set previously? Maybe next time I again want to
produce uniformly distributed random variates, and set seed 100 by accident
, which may lead to the variates produced is not random.
Thank you for any replies!
Sincerely,
from Rose.
