Discussion:
CTABLES

Funding the implementation of a fully blown CTABLES at commercial rates,
I think would cost well into 5 figures.

However, it is perhaps possible, that a smaller subset of CTABLES could
be undertaken by an altruistic programmer who has some time on his
hands and wishes to earn a bit of money for a few months.

The problem, is (and this is where big companies have the advantage) most
programmers are not good administrators. To crowdfund such an exercise
one would first have to agree on which subset of CTABLES to undertake.
That means, a detailed specification, with examples showing exactly what
would be expected, which features of CTABLES should be included, and perhaps
more importantly, which are not expected. Once that has been agreed,
an estimate of the time and cost could be prepared an appeal for funds could begin.
This kind of organisation, takes skill and effort, and would probably
have no tangible reward, unless some percentage of the total was agreed
beforehand.

I think we have to find somebody who has done that kind of project steering
before (I haven't). Can everybody look into their contacts to find somebody
who would have the skills and will to steer such a project?

However I'd volunteer to participate in the workgroup defining the priority
of the functions of the CTABLES command. Maybe Frans and Alan would want to
join?

I agree with John that a commercial implementation would produce 5 figured
cost. I've already talked to a programmer on this and he came up with the
same estimate. So doing it commercially seems to be no way forward.

If the developers agree, it could generate a funding campaign to implement the command CTABLES on PSPP.

While donations are received, a team can define the characteristics to be implemented and its estimated price.

What does CTABLES do? And what aspects of CTABLES would be critical for
users? I think a plan should be the first step. If CTABLES were part of
PSPP, is the output OK? Or would that be the next hurdle to using PSPP
that the output isn't the same as SPSS (e.g., I find it harder to
copy-and-paste from PSPP into LibreOffice than SPSS; when you copy a
chart from SPSS for Windows, it's actually placing several versions of
the chart in the paste buffer). If the output won't ultimately be
useable, that makes adding CTABLES a waste of time...

Also, I'm sure CTABLES is very important to some people but a lot of
SPSS users probably have never used CTABLES (just like they've never
used any of the other special modules SPSS publishes or even the new
features like python scripting). I think that contributes to its absence
in PSPP.

Finally, I know how statistics are calculated, but not only don't I know
what CTABLES does but I understand that the emphasis is on simply
tallies across complex breakdowns... I don't have any feel for how one
efficiently does this in code.

BTW, I think a better big project would be to enable PSPP to read the
SPSS output format. I know Ben enjoys reverse engineering things.
Thanks largely to Ben and PSPP contributors, the SPSS file format is
widely read (e.g., the R foreign package is based on Ben's code to read
SPSS .SAV files) but the output is completely opaque to all programs
except SPSS. In fact, it's worse than that because there are versions of
SPSS that won't read other versions. That's actually a huge problem for
people who used SPSS to analyze data and all they kept was the output
files or anyone who ever saved the output in the hope that they could
read it years later....

@Frans
I do not think the discussion here is about other features. I think there's a group of people who could organize and work for CTABLES in PSPP.
Moreover, the macros are not an agnostic solution ... may be different languages to choose from and for the end user means learning more than SPSS / PSPP to use a special function.

@Alan
Agree with you, the work done by Ben  is magnificent. If I'm not mistaken, only lack support for SPSS production job  and SPV files. Under the same argument, it would be very useful for all PSPP command had its counterpart in PSPPire.
But I insist that if there is a group interested in operating CTABLES, we must support it. Any further new feature compatible with SPSS should be welcomed.

I've done a lot of the work needed to figure out the format of SPV
files. I'm working on publishing a format specification. Then I'll
work on implementing a reader for it.

Would it be useful to add support for SPSS production job files? That
would not be hard (much easier than SPV files or CTABLES). I'd need a
bunch of examples of the format.

Thanks,

Ben.

That is great news. If you need more files of type SPV/SPO could ask another topic of discussion.

From my point of view, production jobs are very useful to automate lengthy and complex processes that are made recurrently. As PSPP add more commands, the more useful they will be in the future.

However, I think it may only be used interactively and locally directly or by creating a external automation script, and the second way is through the use of IBM SPSS Statistics Server.

At some point I'll need some more to answer a few lingering questions,
but I can already extract all of the important content.

I'm not sure if I get the discussion under the label CTABLES here: why
should "production jobs" replace CTABLES?

Or is it just that there are 3 open topics by now
1. CTABLES
2. Production jobs
3. Reading .spv files

and the discussion is on which to focus time and energy?

Anybody give me a hint, please.

I’m posting this from what you might consider ‘bystander status’ only. I read the posts because I once used PSPP regularly. I never used PSPP as a statistical tool but used it to assist me in manipulating data. I work at an educational institution and my job as statistics officer is more about passing on student data than doing any research. (I suspect most of the people I provide information to would not know a statistical test if it got off the paper and bit them on the bum.) As part of the job I need summary information of our enrolments for my own needs and in response from requests from others (mainly counts or sums, sometimes means or percentages) and never more sophisticated than that.

PSPP has limited capability to summarise data in the way I need it. It worked very well to manipulate data. Consequently, I persuaded my boss to buy SPSS. I wanted SPSS because of my previous experience in SPSS using TABLES, and that was the prime reason form moving away from PSPP to SPSS. Unfortunately, SPSS does not offer TABLES and has implemented CTABLES instead.

I have to admit to not being particularly impressed by CTABLES. Perhaps I just need more practice using it as some of the SPSS gurus think it’s the bees knees. I much preferred the old TABLES that I used to use with SPSS v10. I prefer to write code that point and click, and CTABLES is bit of a challenge in that regard whereas TABLES was quite simple.

I will move back to PSPP when a version of (C)TABLES is installed.

At some point I'll need some more to answer a few lingering questions,

Production jobs are a separate topic, and John has changed the subject
for the emails that focus on production jobs (thanks, John).

SPV files have more to do with CTABLES than you may realize. CTABLES is
a heavy-duty application of pivot tables. It relies on a lot of
features that aren't well documented for SPSS; the various SPSS
explanations of pivot tables are terribly vague. The SPV file format,
however, is a pretty clear specification for how SPSS pivot tables
really work, and once I came to learn about it in detail I understood
much better how output formatting really works. So this is an essential
building block for CTABLES and will be important for eventually
implementing it.

Hi Ben

Thanks for the comprehensive explanation why CTABLES depend on the ability
to read SPV files. Do I understand correctly that this dependency comes
only from the pivot-function in the SPV file - meaning that you doubleclick
on a table to change pages?

I mean by that the following: The syntax of CTABLES is:
"CTABLES downvariable BY acrossvariable BY pagevariable"
Pages are shown in the SPV file only by doubleclicking and choosing another
page.

The function is a pain anyway because it is uncomfortable and also (at
least for me) not working under all circumstances. So I can confirm Alans
arguments on this although I have no idea why rendering a new page is not
always working.

To come back to the topic of implementing CTABLES:
1. Can we avoid the dependency on understanding SPV if we strip the CTABLES
command of the page function? So to support only 2 dimensions in the
output? This is probably what most users need.

2. Or do you think that is not worth to do, because once the SPV issue is
solved the whole CTABLES output would have to be reprogrammed? Or are there
other functions of the CTABLES command (like plots or graphs) that depend
on the SPV issue, too?

3. As I do not have any knowledge about TABLES: does TABLES have the same
dependencies on pivot and SPV? Would it be a solution to come back to the
proposal of ftr and Frans to opt for TABLES instead of CTABLES?

Pivot tables are a lot more than just pages, and CTABLES is pretty tied
up with the pivot functionality.

This may be an issue, too, although I doubt that plots or graphs would
be in a first draft of the CTABLES functionality.

I haven't studied TABLES in the way I have CTABLES. I suspect that
users are more interested in the latter, because it's come up again and
again over the last few years, whereas the former has hardly been
mentioned.

ok. That means for me, that we should abort the request for CTABLES until
the SPV issue is solved.

1. Has anybody a different opinion?
2. Ben, do you have any idea about the time needed so that we do not rise
the issue with CTABLES again and again?
3. Maybe Frans idea about implementing !Macros could serve as a workaround.
I think that might be worthwhile to discuss. Any opinions on that?

I think we should take this issue calmly. The SPV format is a way of showing the results dynamically allowing it to be edited later form or convert them to another format, etc. If it's just a broad topic.
I think the important thing here is to collect information relevant to the implementation of CTABLES and also encouraging support for the work that needs PSPP project.
Hands who can write code is needed.

From my point of view, the implementation of macro is very different and deserves a discussion in itself.
I imagine PSPP priorities are implementing more compatible SPSS commands that equate to the basic package. I think at this point, is unproductive talk about macros.

The value of (C)TABLES for me was the ability to publish the output without making edits, and that was always a 2-dimensional table. Never a 3-dimensional table. (More gimmick than value.) An additional value of (C)TABLES was also the ability to nest variables and include sub-totals, often 2 deep, sometimes 3 (but not often). Seldom used statistics. Mostly count and sum.

tables and I have not been able to do so thus far.

The implementation of macros is a big project but I'd say that it's
simpler than SPV or CTABLES. It's also completely independent of either
of those.

Ben,

When we use modern versions of SPSS, I often scroll down to elements of
the SPV file and that element is replaced by a message like "Please
wait - computing" and then after a few seconds, the content replaces
this message. Is this something that you've encountered and
successfully understood? If so, what's SPSS doing? Is it really
re-computing the element? That would imply that it saved all the data
into the SPV file, which seems like an odd and potentially sensitive
issue. I cannot say what elements do this, but I can recall seeing it
occur for graphs.

I've also heard, but cannot confirm first-hand, that when there are
added modules in SPSS and those modules have been used to create
oiutput, that the viewer of the SPV file must also have those modules or
else the computing message never goes away (because the viewer doesn't
have the correct code to replicate the analysis). This also seems like
extraordinarily bad thinking (or at least has extraordinarily bad
outcomes for users). But, again, I cannot say I've seen this first-hand
nor do I know if that applies to all modules.

I haven't used modern versions of SPSS, so I can't say how the user
interface behaves, but an SPV file does contain all of the data that
appears in the output. (Otherwise it would not be possible to
distribute an SPV file independent of the SPS or SAV files.)

If I had to guess what happens when you see that message, I'd say that
it's closer to SPSS "rendering" the output element than "computing"
anything. Because an SPV file is a fairly abstract representation of
output, something analogous to an HTML table plus CSS styling, a program
that displays an SPV file has to do a lot of work to render it in a
pretty way.

I bet that applies only to specialized forms of output. All pivot
tables in an SPV file share a common format, which does not require the
viewer software to recompute anything from the original data (only to
render the table), so there would be no reason for it otherwise (unless
SPSS restricts it for business reasons, to sell more of the extra
modules).

How would they be more useful than any general method of automation?

For example, if you wanted to automatically download a file from a
location on the web, and analzse that, you could write a 3 line shell
script using wget and pspp. You could even have cron run it every
day/hour/minute and upload the results somewhere.

I'm sure it would also be possible with "production jobs", but I wonder
what the utility is, reinventing the wheel to do something which can
already be done.

I agree with you, however, a few years ago when I had no more knowledge of computers, I would not have said the same.

This is not to reinvent the wheel, but to offer a method that many users already know. 
Such functionality in PSPP, could be available on any platform, and you have a group of users who would know how to use it and also count with SPJ files they did or their companies gave them, saying, "with that file, analyze X data with Y statistical".

Everything depends on the perspective.

Hi Charles and John. I'm very sad with this answer.

I have general knowledge about computers, linux, cron and others, but I
think that my collegues at the University dont't share this knowledge. Easy
is better, and if the automation is in the same environment, these is the
best.

I would guess that SPSS users are used to them and that they may have
some that they consider valuable.

I personally never use production jops and also never save .spv files but
export results to excel. But I might be untypical.

Correction: Do I understand correctly "production job" = "marco
functionality"? Than I use that.

ISO 20252 on market research "forces" to save all the processes have been
executed in a database so someone else could repeat exactly the same
processes as the first time.
This forces to save the syntax of all the processes running. Each process
that can be used in "production jobs" will be welcome, especially those
that affect the transformation of the database.

Syntax is saved anyway. Furthermore, it is no bad idea to save a "program"
(=clean set of syntax) for all transformations and tables in case you find
errors in the data after you have done tabulation and want to start anew.
But this is probably not what Alan and John were up to discuss?

Same with me. In survey analysis you have more ad-hoc analyses , so less
repetition.

I am far more interested in using MR and CTABLES.

Please do not confuse the topics of discussion. Currently PSPP developers donate their time voluntarily. They decide on what functions/features can (and want to) work.

No more we ask, they will perform.


Those interested in adding the "CTABLES" command, can contribute to the discussion on the mailing list for that issue, adding useful information to begin work collecting money, incentives, company that could do the job, etc.
Moreover, if anyone is interested in SPSS production jobs, you can send sample files (SPJ and SPS files).

Thanks

CJT
