Combining variables

Dear Friends,
I was given a project with an N=26 that has 28 outcome variables and three stress variables (explanatory). I'm not able to touch the outcome variables, but I will be able combine the three stress variables; here is where I need help.
The correlations between these variables are: 1 & 2 = .456; 1 & 3 = .157; and 2 & 3 = -.077. Equal unit weighting doesn't appear to be a good idea. I generated a component score using PC. However, I'm not sure if there is a better way of combining these measures.
Any suggestions (and or references) will be most welcome. TIA.

Question on 16: production facility

All,

I just got 16 installed and while I'm certainly not looking forward to it,
there's no choice for site licenses.

My question: in the program listing, there used to be an entry for
'production facility'. There is not now on my installation. The only entry
is for 'license authorization wizard'. I'm assuming the production facilty
hasn't been done away with so how do I now access it?

After looking at the so-called legacy viewer, I noticed that the export
feature has been stripped out. This seems like a rather stupid decision as I
can easily see needing to export chunks of 15 output to a text file. The
other odd thing is why the legacy viewer was not incorporated into the 16
file open output. I don't know anything about the underlying code but it
would seem to be trivial in difficulty. Probably both decisions were driven
by marketing. I'm guessing that 17 is either in production release or late
beta. So, I'm curious, does 17 support 15 and before output files?

Go to Help and type Production Jobs into the Index box--you'll find all the
details on how to define and run a production job. Job creation is now
integrated into SPSS.

It'd be nifty to know which scheduling utilities we're supposed to use

Re: Question on 16: production facility

Does anybody know what could account for this - when double-clicking a
production file (*.spj) or running one via schedule, SPSS will launch
but the file won't execute. (?)

Here's the syntax file the production job comprises:

* test production job *.
data list free /v1 v2.
begin data
1 1
2 2
3 3
end data.
save outfile = 'c:\temp\production job test.sav'.

Thanks,
-Gary

Re: Question on 16: production facility

SPSS owns it but doesn't execute it. To execute it you have to run it from
the command line using the appropriate command line parameters or wrap it in
a bat file containing the command line.

Re: Combining variables

In reply to this post by Salbod

Dear Stephen

If the variables can be considered 'formative' indicators you can sum them
to form a scale without worrying about the correlations between them. For
example if the variables measured stress coming from independent sources (eg
work, family) you would not necessarily expect them to be correlated, and
you could add them to get a 'total' stress. The legitimacy of this
procedure rests on substantive rather than statistical considerations, and
needs to be based on your understanding of the content area, & how the
questions are worded etc.

Regards
Garry Gelade
