Therefore, we need to consider some efficient ways to optimize memory usage in Stata. If you are using 32-bit Windows XP and you are still having trouble allocating memory, you should read “Memory allocation in Windows XP”. The big advantage of -set mem- is one can set it for a specific job and then know that as one does other things, stata can still run because it has the memory it needs. 5. 0 ? It may be worth remembering that sample size estimation is the art of getting the required amount of precision with the minimum data. Therefore I need to set an upper bound on memory usage (indeed Stata already crashed the system). frame Dear all, I have a computer of 3 GB RAM memory on which I use Stata 10 MP2.
