I have Stata 8 (SE) on the desktop and laptop. The desktop version is
recently updated (update all) including swapping the executable. The
notebook stata 8 is just what came off the CD. I ran the exact same
two-level Nlogit (7 nests, 43 choice) on both machines, with the
maximization options d1 and difficult. On the laptop it converges
nicely to a LLF=-1810. On the desktop there are no warning messages but
it converges to LLF=-1811 and several standard errors are missing. The
files are exactly the same on each machine (I copied the files from
laptop to desktop and ran them without any changes to make sure). Can
anybody explain why there is this difference and tell me whether the
convergence results on the laptop are trustworthy?
Thanks in advance.
