st: Re: RE: Random number seed
You are right.
Once I open stata and generate random numbers, the seed keeps on changing
and it is completely randomized.
But since the program is long, I am running it without opening stata. I am
running it in the batch mode giving the command
stata -b do market.do
This program opens stata each time and hence gets the same seed and the same
set of random numbers each time.
