Since I can't use SAS to do analyze at PC Lab, due to Go Back and hard disk limit in PC Lab, I decide to do it at home.
Since I don't have SAS and it cost $50 for student version and only work for 3 months, I decide to use something free.
So I found OpenStat, a freeware which can do lots of statistics analysis.
It has both windows and Linux version.
Now I use SAS at school to translate data to CVS format, but I think I should write a translator to do that for rapidly use.
