Re: st: Weights

First, Martin should note that SPSS does not have some magical way to hold data
more compactly than Stata can. You just need to pick the proper storage types
in Stata. I would guess that there are variables being held as doubles or long
strings that don't need that much space. To get the most useful advice, you may
want to -describe- one of your dataset chunks so that we can see where the
storage is being used up.
I often work with fairly large datasets (~1 GB) and one suggestion that I
haven't seen mentioned thus far is to use -recast- with the force option to
convert doubles to floats when feasible. I find that compress will rarely
convert a double to a float even though the actual number is stored with far
less than float precision. .
