SPSS PC is NOT SPSS! At least, it's not all of it.  If you run SPSS
Windows or SPSS OS/2 instead, then you'll have ALL the commands you have
on the VAX.

Speed depends on LOTS of factors like whether you're getting a real i486
or one of those cripples that leaves out the FPU or the cache.  Are you
getting a 32-bit bus (for what your doing an EISA or 32-bit MCA really

computer?... About 2/3's of a Mac Quadra!"  ;-)
Most of what you're doing will be I/O bound (SCSI 2 probably would be
worth the money in your case).

My personal experience comparing SPSS on the desktop with SPSS on a
mainframe (in our case an IBM ES/9000-150) is that the mainframe is
beaucoup faster (mainly because it's expensive data disks are loads
faster than even SCSI 2), but the effect of time sharing is that the
total time between starting a job and having the output is pretty nearly
a wash (your mileage may vary :-)

Frankly, I much prefer running SPSS on a desktop machine because I have
greater control over the process.  If I make a typo I know right away
that applies here because of the inherent difference in standard diskb.

Finally, to the extent speed really is important, there is the

that applies here because of the inherent difference in standard disk

If I am not mistaken there was some recent discussion of completing a Q-mode
factor analysis upon data in SPSS.  It was stated correctly that the flip
command will place the data into the suitable format for attempting a Q-mode
analysis, i.e., the observations become variables and vice versa.  However,
if anyone is going to attemp this procedure you MUST standardize the
variables before flipping the observations and variables.  If you don't your
results will probably show almost perfect correlations between observations,
and thus one general factor being extracted.  The reason for this problem
lies in the scale of different variables.  For example, if you are working
with socioeconomic data it is typical to have most variables in rated form
while having a variable like average family income measured in dollars.
This poses no problem in standard R-mode analyses since the average family
income variable is standardized as are all the other variables.  However,
when you flip the observations and variables, SPSS will standardize across
an observation not a variable.  Therefore, the differences in the scale of
measurement will profoundy affect this standardization attempt, and thus
when the observations are correlated among one another they will be very
similar.  This similarity, again, may only be due to the different scales of
measurement across the variables.  Believe me, I have found this out from
experience.

First, ask your local consultant.

Perhaps, some commercially-written numerical-software libraries are available
on your machine.  Ask him/her about the IMSL and the NAG libraries.  These are
two high-quality, well-documented, libraries of FORTRAN-callable subroutines.

If neither are available, then there are some libraries of software available
via FTP (File Transfer Protocol) on the Internet.  Connect to the site named
'RESEARCH.ATT.COM', and answer 'netlib' to the "name" prompt, and supply your
ID to the "password" prompt.  Then, select a specific directory or get the
"readme" or the "index" documents from the root-directory.

Of course it depends what you want to do and what platform you
are on --
But unless you are doing esoteric statistics SPSS will do a great
almost anything you want. You can write your own Fortran procedures
to use as procedures in SPSS -- a lot is already done for you that
way.
IMSL is very useful either to write standalone procedures or
to incorporate in SPSS procedures.
since you are at a university, the odds are high that
both SPSS and IMSL are available to you.
IMSL is the International math & stat libraries
I have no connection with either SPSS OR IMSL except for
being a satisfied user for 20 or so years.

Thinks this is probably not statistically sound but....
1. select if just the three groups
2. do discriminant and record the discriminant function and cut-offs
3. then calculate and assign for the remaining group.

----------------------------Original message----------------------------

VERSION:  SAS 6.07
OP/SYS    CMS

Problem: Using the SPSS "GET SAS" Command with files written with SAS 6

Hello, Net...
I haven't seen any mention of this, so perhaps others are not having
this problem:
  Using the GET SAS command on a file written with SAS V 5.xx works
  (usually) just as advertised....BUT...I have been having problems
  with SAS files created with SAS 6.07 (the V 5 engine is specified).
  PROC CONTENTS in 6.07 recognizes this as a SAS V 5 file, as does
  PROC CONTENTS in 5.18.  SPSS fails with an I/O error on it, however.
  Anyone else had this problem?  I should add that the same tests done
  on MVS/TSO ran without any trouble.  One (possibly) interesting
  addendum: the filelist descriptors show 2 records for the
  "real" SAS v 5 library but only 1 for the library written with
   SAS 6 (V 5 engine)???  Is SAS doing something odd here? am I?
   Is my system?  Many thanks in advance.

The "factor matrix" is the unrotated matrix of factor or component
loadings. It is the solution to which the final statistics apply.

ULS and ALPHA methods both allow the iterative algorithm to continue
iterating when impossible estimates for unique variances occur (Heywood
cases). They obviously don't constrain the factor loadings, as evidenced
by the values given above. They do constrain at the point of calculating
communalities. Is the solution trustworthy? Maybe. To the best of my
knowledge, there are no unique issues introduced by FACTOR's handling
of Heywood cases.

If they are, how could we install them? And how a user could "map" his data

Also, are Statistics Canada maps completely redundant with the CANADA map

Comments: To: sas-l@UGA.BITNET, spssx-l@UGA.BITNET

Problem: Using (CMS) SPSS's GET SAS command to read a SAS Lib from V 6.07
System:  VM/CMS
Versions: SPSS 4.1, SAS 6.07

Hello Netters,

I recently asked whether any other CMS sites/users were having problems
using the SPSS command GET SAS with SAS Libraries created under V 6.x
even when the V5 engine had been specified.  The answer was (and I
quote) "yes".  I will add that this works in the MVS/TSO environment,
and it works when the Library file is created with SAS V 5.18.
I would like to thank all who responded: Melvin Klassen, Lisa Wayte,
Bill LeBlanc, Douglas Mills, Sally Muller and Ron Fehd.  Special
thanks to Margie Gurwit.

I also spoke to both SAS and SPSS Tech Support: SAS pointed out that
the header was slightly different for a file created with Version 6,
the "creating" (or whatever they called it) version is shown as "85.00"
instead of "85.18".  SPSS said I should use the V5SEQ seq engine, the
Library should have a filemode of _4 (ie TEST SASV5 A4), I should have
a tdisk available and might need to increase buffer space (SPSS pgm (150K
- is how I tried it).  None of these exactly worked, but they pointed in
the right direction.

Then Margie Gurwit sent a reply: use XEDIT to change the 85.00 to 85.18
on that first line (col 43-47) .... it worked!  Why?  Who knows, it can
wait.

On a more serious note, I think there would be problems XEDITing a large
SAS file, so you would need a program to do this.

I believe SPSS V 5 (due, I believe, 1st qtr 93) will be able to handle
SAS (portable?) files, but that is unconfirmed (anyone have any info?).
The (SAS) SPSS engine is a big help for those of us who provide support
to users of both packages on various platforms, as has (SPSS's) GET SAS,
although it has been available only on IBM platforms.

Short answer. You can't get labels output from LIST but you can from
REPORT, so use "REPORT FORMAT=LIST / VAR=x y z (LABEL) / BREAK=(NOBREAK)."

Explanation. Partly historical. LIST has been in SPSS from the start so
is a procedure of the "old school" - minimalist command, standard output.
REPORT was added in the 70's by which time folks had got more demanding
and were willing to flog through  ore complex commands to get control
over the output. Also partly functional. LIST is explicitly a command to
show you the data "as stored", so it might be confusing to show a text
value when the variable is numerically coded. Having a separate command
to generate "reports" for external consumption without reference to the
data makes sense.

Footnote. That REPORT example is still minimalist. For example, I'd
certainly incorporate white space to guide the eye ("FORMAT=LIST(5)")
and probably choose explicit column widths and headers for each variable.
Also add page headers, select a page length suitable for printing on
portrait paper, choose a different MISSING VALUE marker than "." etc.
On the other hand, after any set of data transforms I'd recommend a
qick "LIST /CASES=5".
