Re: Is There a Way in SPSS/SAS/Stata to Do This Type of Conjoint Analysis?

Hi there,

I have the following datasets including 10 questions which respondents have
to answer following questions: "If UFA introduce a new store in your
community, could you tell me which factor is most important?"

1. Staff's knowledge/Product Quality/Both;

2. Store Location/Offer only Lifestyle Product/Both;

3. Price/Staff's Knowledge/Both;

4. Product Quality/ Store Location/Both;

5. Price/ Offer only Lifestyle Product /Both;

6. Store Location/ Staff's Knowledge/Both;

7. Product Quality/ Offer only style product/Both;

8. Price/Staff's Knowledge/Both;

9. Staff's Knowledge/Offer only Lifestyle Product /Both;

10.Price/ Product Quality/Both;
That is, each question compares two characteristics and the respondent has
to state which of the two is more important or both. I now want to specify
which of the factors is the most important overall? Which type of the *Conjoint
Analysis is it? *, Is there a way in SPSS/SAS/Stata to do this type of
Conjoint Analysis?

Thanks for your help

Hans,

What you are trying to do is a series of paired comparions with a rather
incomplete design. There is a great deal of literature on the subject going
back 80 years to Thurstone's 1927 paper, "The Law of Comparative Judgment".
In recent years, Jordan Louvier has written extensively on the subject.
I've found the best current implementation of the approach to be Sawtooth
Softwares Max-Diff procedure which on the front end produces a very
efficient design and on the back end utilized hierarchical Bayes Regression
to estimate importances at the individual level. The company'e technical
paper at http://www.sawtoothsoftware.com/download/techpap/maxdifftech.pdf is
a good review of approaches to your problem.

Errors in Python examples

Hi,

For my own understanding I'm running some Python
examples given in SPSS programming & data management
(4th ed), but sometimes I get error messages. For
instance, the example given on p. 481
(python_cursor_Set_ValueNumeric.sps). I'm just
copy-and-pasting the code (and adding indentations
where necessary), so why the error messages? It says
''Cursor' object has no object 'running'.
TypeError:__init__() got and unexpected keyword
argument 'accessType'

I am using SPSS v14.02, Python 2.4.

Thanks in advance!

ALbert-Jan

Cheers!
Albert-Jan

Re: Errors in Python examples

The 4th edition of the Data Management book goes with SPSS 15. The example you cite requires that version. As it says in the Preface,

This edition has been updated to include numerous enhanced data management
features introduced in SPSS 15.0. Many examples will work with earlier versions, but
some examples rely on features not available prior to SPSS 15.0. Some of the Python
examples require SPSS 15.0.1 or later.

HTH,
Jon Peck

In reply to this post by Albert-Jan Roskam

The 4th edition is intended for use with SPSS 15. I don't think accessType was supported in SPSS 14.

Re: Errors in Python examples

Thank you to all who replied! I just downloaded the
3rd edition of SPSS programming & Data management,
hoping that all examples will work with spss v14. But
hopefully my company will upgrade to v15 or v16 soon!

Cheers!!
