st: different output in different machines

["Prado De Castro Alfaiate, Jorge" <jprado@essex.ac.uk>]

Dear all,

I have written a code that delivers a different output depending on the computer in which I run it. I am controlling for the version, which is STATA 10. It is a mle, and in one computer I get a log-likelihood of, say, 1.176456, while in another computer I get, say, 1.1686789. That is, the results are not radically different but they are different enough so that they deliver significantly different coefficients in my regression. Also, the speed of convergence changes (from, say, 25 iterations to, say, 32 iterations). I use the exact same dataset and do-file in each case...

Could anyone give me a clue about what may be causing this curious problem?

Thanks in advance,
Jorge
