Is Mult Response Crosstabs an add-on procedure?

David Thompson
I have the basic package, plus Regression and Advanced Statistics (all v. 19). Do I have to pay extra to access Mult Response Crosstabs? I can access Mult Response /Frequencies...

From the FM:  "MULT RESPONSE is available in the Statistics Base option."

Also from the FM:

Example

MULT RESPONSE GROUPS=MAGS 'MAGAZINES READ' (TIME TO STONE (2))
  /VARIABLES=EDUC (1,3)/TABLES=EDUC BY MAGS.

* The TABLES subcommand requests a crosstabulation of variable EDUC by the multiple-dichotomy group MAGS.

AFAIK, Mult Response/Frequencies IS where you do Mult Response crosstabs.
However, you must  first define mult response pseudo variables, then do crosstabs on them.

Yes, it let's me run /TABLES using the MULT RESPONSE command, but I can't get Chi Square values that way. If I run CROSSTABS after defining the variables with MULT RESPONSE, it gives me an illegal variable error.

Grrr.

Bruce Weaver's example using syntax is by far the easiest way to do mult repsonse crosstabs.
I don't have  SPSS access right this moment, but my recollection is the gui/menu
approach to mult response is klunk and split into two parts.

I am using syntax vs the GUI. I can produce the tables using MULT RESPONSE, but can't get Chi Square values that way.

You can also create crosstabulations with the MULT RESPONSE command, using the TABLES subcommand:

MULT RESPONSE  GROUPS=MAGS 'MAGAZINES READ' (TIME TO STONE (2))
  /VARIABLES=EDUC (1,3)/TABLES=EDUC BY MAGS.


You cannot create crosstabulation of multiple response sets with the CROSSTABS command.

If you have the Custom Tables option, you can also create crosstabulations of multiple response sets with the TABLES command.

I do not believe that mult response has ever produced stat tests like chi-squared

Your belief/recall is correct however the 'what is counted' reason is *NOT*.
In the Chi Square statistic what is the fundamental assumption?



Drum Roll.......

INDEPENDENCE!!!!

In a multiple response scenario that clearly does not apply!
Important to realize that the Chi Square Statistic is actually a statement of how well the data fit a MODEL!!

What is this model?

That the distribution of the row variable is INDEPENDENT of the distribution of the column variable?

What does this mean?

That the cell proportion EXPECTED under the MODEL can be expressed as the product of the proportion in the row and the column marginals.

ChiSqu = SUM ((O-E)**2/E)
....
Go find a book!

Anytime you see someone discussing/defending the use of  Chi Square with multiple response data you can conclude.
1.  They are utterly full of crap?
OR
2.  They are incredibly sophisticated and have some awesome formula for correctly expressing the terms E  which AFAIK is very complicated to solve!

Re: Is Mult Response Crosstabs an add-on procedure?

David Thompson
Not wanting to be full of crap (and having 25 years of Life since my last stats course), please give me some stats advice:

I received a small data set from a colleague who conducted a survey using Survey Monkey. He surveyed professionals (n=78) about their use of specific instruments (n=3), and asked them to endorse one or more attributes of each instrument (total attributes for each instrument=18). Not all respondents rated all three instruments, although some did. The 18 attributes were dichotomous. Some respondent variables were also collected (geographic region, experience, training).

My colleague is interested in understanding the differences between instruments and their attributes as rated by the respondents.

Given the lack of independence of the data, what would be an appropriate analysis procedure?

Re: Is Mult Response Crosstabs an add-on procedure?

It's been far more than 25 for me (somehow I am permanently cursed)!

"what would be an appropriate analysis procedure?"
It is unclear as to how what you originally described applies aside from an 18x18x18 something or another mapped onto demogs and what not.
Let's see, get about 20,000 more subjects and you might be able to do something 'statistical' with it.
Meanwhile, probably best to stick with some tables and pretty pictures or hire a survey 'statistician' to cobble together some 'lies' and tie a nice ribbon around it.

Not all respondents rated all three instruments, although some did. The 18

Re: Is Mult Response Crosstabs an add-on procedure?

Jeanne Eidex
In reply to this post by David Thompson

Hi David,

 

Here’s what I think…

 

1)      The amount of data, both in terms of base size and number of variables is very small, so, you can run some straightforward percentages and means to report back to your friend.

2)      Your base size is very small and can’t be broken into subgroups for much useful analysis, n=78; so, for the most part, you can just use straight frequencies to report your information (% of people from each region, average years of experience, etc.) or you can run some descriptive, but, make sure all of your blanks are showing up as system missing and are not 0 filled (unless you want them to be).

3)      For the multiple response situation, I don’t think you need cross tabs, just do the following…

a.       Define your multiple response variables through the menu (I’m a syntax girl but the menu is convenient for creating this syntax).

b.      Use the menu to run a multiple frequency on the data; and paste the syntax into the syntax editor.  It will look something like this.

MULT RESPONSE GROUPS=$Q_ATTRIBUTES (qs6_1 qs6_2 qs6_3 qs6_4 qs6_5 qs6_6 qs6_7 qs6_8 qs6_9

qs6_10  qs6_11 qs6_12 qs6_13 qs6_14 qs6_15 (1))   /FREQUENCIES=$Q_ATTRIBUTES.

c.       Then do it for each group and highlight and run the frequencies.  Print them and then use the data to create a nice bar chart in something like PowerPoint that compares the 3 instruments.  As for statistics, your margin of error is +/- 11%; therefore, differences greater than 11% are not going to be due to sampling error and that might be a safe way to look at it. 

d.      By the way, I am not sure how the data is set-up, my response is based on the assumption that you have 3 sets of 18 Attribute dichotomy variables, one for each instrument.

 

Good luck and enjoy your analysis J,

Jeanne

Re: Is Mult Response Crosstabs an add-on procedure?

In reply to this post by David Thompson
I don't see any use at all for mult response here.

For the most part, after simple tabs, you don't want to bother with
most of the individual items -- Pick out a couple of the items, if they
are really pertinent, but use the 18 to make two or three summary
scores/ composite scores. 

Everything "good" can go into one total, for best performer -- maybe
that uses all 18 items, after reversing the scoring where needed.
Also make two or three totals that use subsets of items, preferable
not overlapping. 

You can look at overall averages, but your best tests will probably be
from the paired t-tests that you can run, using just the data were
raters have rated two instruments.  - If you want to look at a single
dichotomous item, that becomes the McNemar Test for Changes on a
2x2 table, which uses only the off-diagonal cells:  This is essentially a
Sign test on the subjects who give opposite ratings on two instruments.

You can look at the demographic variables to see if they show different
totals, but the total N of 78 gives you poor power for concluding much,
even if there seems to be a difference.  (This wasn't a random sample
of anything, but just a "sample of convenience," right?)

Re: Is Mult Response Crosstabs an add-on procedure?

Taking it another step or two:
IF one had a huge sample it would be interesting to see how the various patterns of the attribute endorsements emerge.  But since you don't do NOT bother to do anything with the following!
---
Ie With 18 attributes there are
C(18,2) 18!/16! 2! = 18*17/2=9*17=153 possible pairwise selections.
These could be directly analyzed using some form of dimension reduction technique (I am being deliberately agnostic here).  However with only 78 respondents this is just GIGOnostication.

Getting deeper:  
Why stop at 2 way relationships.  Quite possibly 3 way and 4 way patterns are interesting and could form the basis of identifying stable dimensions of the attribute set over and above pairwise relationships.
However there are
18!/15! 3! =272 possible triplets.
18!/14! 4! =3060 possible quads.
153+272+3060 = 3485 combinations of possible interest even if one only considers joint endorsement up to level 4.
----
So?  who cares?
Well, are the frequency distributions of these patterns the same over the 3 instruments?
Do they vary according to demographic profiles etc?
------------
Analytically?  Real fun but I'm not going to go there today!
---
But as is obvious, 78 cases is NOT going to give squat!
---
I have thought about this kind of thing a lot over the years and the resulting bramage is one reason why I try to avoid marketing research like the plague.
