I believe the memory limit depends on your operating system and how it is configured. To my knowledge Stata (SE) places no effective limit on the overall size of the data file you use. I have allocated 5GB of RAM to Stata on a Unix machine without a problem.

As for my knowledge, I do not think it is possible for Stata to use 17 Gb data file. Even if you computer has 5Gb of RAM, an operation system ( I used UNIX server once) may give for Stata only 2GB. best, sasha Ramani Gunatilaka wrote:Hi all,

Stas Kolenikov's Shapley.ado allows up to 56 variables. I am trying to do a decomposition with 29 variables. But the zero-one matrix for 29 variables would require 16896 MB of memory (ref. http://www.stata.com/support/faqa/data/howbig.html).

Stata doesn't seem to have a problem generating the matrix (I tried it upto two gigs before realising that my computer won't have enough disk space to store it).

But even if I were to use a more powerful computer, I am worried that Stata may not be able to use this file. Can someone please tell me, which version of Stata for which windows operating system can handle this large a data set? Also, roughly how much RAM would I require and how much free disk space?

I referred all the FAQ's and didn't come up with anything very useful in relation to my particular question.

Thanks in advance,

Regards,

Ramani
