If you want random data, you can install
the MakeDataWithCases dialog box from the SPSS Community website (www.ibm.com/developerworks/spssdevcentral).
It will generate data from any of 22 (or is it 23) probability distributions.
It can generate correlated or uncorrelated data. Prerequisites
are detailed in the download.
It works by generating an INPUT PROGRAM
and then optionally using MATRIX to generate correlations by linear transformations.
That, of course, changes some of the distribution families. I'm
thinking about some more sophisticated ways of generating correlated variables.

[SPSSX-L] Simulation
with SPSS

I found an old thread apparently starting a discussion
on simulation, but the
OP didn't respond to a clarification question, so it seems to have died
long
ago. I am interested in creating simulated data sets for student
use. I
want to ensure that the data sets have the appropriate characteristics
for
weekly discussion. I assume there is a mechanism for creating such
data
sets in SPSS/PASW, but I do not know how to do it. Ideally, I would
like to
begin with very simple descriptive statistics but "non-small"
data sets (not
really large, but a couple hundred observations would be nice).
Can anyone point me in the right direction for a start? I assume
this is
something that must be done through syntax rather than menus, but I haven't
been able to find a primer that discusses it so far.
