Subject | st: Setting same seed, getting different random numbers. |
Date | Wed, 30 Nov 2011 13:29:11 -0800 |
I encountered a strange problem. I tried running the same code on two different versions of Stata - one Stata/SE 12.0 on a server, and one Stata/SE 11.2 on my own computer. Both generate normal random numbers in mata with the same seed. But after a while the random numbers they generate differ! The code is as follows set seed 2 mata f = rnormal(1000000,1,0,1) On the two machines, f[1,1] = .7005116833. But one one f[1000000,1] = -.5182349644, and on the other it is .7083750352. This strikes me as bizarre and impedes replication of my code across computers. Any ideas as to what's going on here?
