Hi, Sam!


Setting seed is enough:

. set seed 1

. di uniform()
.66818523

. di uniform()
.92796107

. di uniform()
.48448141

. set seed 1

. di uniform()
.66818523

However, if you initially set seed to be equal to current time (rather then the constant 1 here) than time matters.

Regards, Sergiy

Just a clarification requested. Nick Cox just seemed to indicate that to
replicate using seed one needs to also reference time. Have I
misunderstood? Or is time an alternative way to obtain a seed when one
does not care what it is? I guess I just want to assure that setting seed
*sets* the seed so that it replicates any other run with the same seed,
regardless of the time.

Thanks a bunch.
Sam
