"Appropriate" may not be the best word to describe what is going on here.
Any seed is a good seed: If you want to redo some analysis that involves the
generation of random numbers, you simply issue the same one again, whether
it is large or small.

"Canceling" can be achieved by simply issuing another -set seed- command
with a different number. You can see something`s changed afterwards by
typing

***
di "`c(seed)'"

Betreff: 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.
