SPSS Syntax for PAMS analysis

Hello,

I found an article that has code for SPSS syntax to conduct a PAMS analysis (see the SPSS syntax at the end of the article: http://www.airweb.org/images/irapps20.pdf). However, when I run this syntax I have two problems noted below.

PROBLEM 1

I have this syntax:

DESCRIPTIVES
variables= dim1, dim2 / SAVE.

I get this error message:

Text: dim1

An undefined variable name, or a scratch or system variable was specified in a variable list which accepts only standard variables. Check spelling and verify the existence of this variable.

This command not executed.

No Variables subcommand.

Second PROBLEM

I get this error message:

Run MATRIX procedure:
>Error encountered in source line #   720

>Error # 12581
>A division by zero has been attempted.
>This command not executed.
>Error encountered in source line #   720

>Error # 12581
>A division by zero has been attempted.
>Error encountered in source line #   720

>Error # 12581
>A division by zero has been attempted.
>Error encountered in source line #   720

>Error # 12581
>A division by zero has been attempted.
>Error encountered in source line #   720

>Error # 12581

>Error encountered in source line #   720

>Error # 12581
>A division by zero has been attempted.
>Error encountered in source line #   720

>Error # 12581
>A division by zero has been attempted.
>Error encountered in source line #   720

>Error # 12581
>A division by zero has been attempted.
>Error encountered in source line #   720

>Error # 12581

>Error encountered in source line #   720

>Error # 12581

>Error # 12581

>Error # 12581

>Error encountered in source line #   720

>Error # 12581
>A division by zero has been attempted.
>Error encountered in source line #   721

>Error # 12364
>Number of column elements is not the same in constructing the matrix.  Number

>This command not executed.

------ END MATRIX -----

By the way here is my entire SPSS code:

Proximities products, consultation, relationship, responsiveness, compensation, reliability

/matrix=out(*)

/view=variable

/measure=seuclid.

ALSCAL

/Matrix=in(*)

/outfile='C:\PAMS\Matrix123.sav'

/level=ordinal

/plot=default

/criteria=dimens(2).

DESCRIPTIVES

variables= dim1, dim2 / SAVE.

matrix.

Get M

/File='C:\PAMS\Data.sav'

/variables= products, consultation, relationship, responsiveness, compensation, reliability.

Get X

/file='c:\pams\matrix123.sav'

/variables= dim1, dim2.

Get ID

/File='C:\PAMS\Data.sav'

/Variables=Excel.

Compute r=nrow(x).

compute col=make(R,1,1).

compute x1={X,Col}.

compute m1=transpos(x1)*x1.

compute m2=transpos(x1)*transpos(m).

compute w=solve(m1,m2).

compute tw=transpos(w).

compute m1=tw*t(x1).

compute k=ncol(m).

compute r=nrow(M).

compute col=make(1,k,1).

compute pvar=rssq(m1-(rsum(m1)*col)/k).

compute var=rssq(m-(rsum(M)*col)/k).

compute col=pvar/var.

compute w={ID,TW,COL}.

Save W

/outfile='C:\PAMs\Individual.sav'.

End Matrix.

Re: SPSS Syntax for PAMS analysis

Hi Brian,

The first error comes from the fact that you do not load the data file
from alscal (Matrix123.sav) before running the descriptives on dim1
and dim2.
The second error comes from the division of the row matrix pvar with
var, which contains values of 0.

Hth,
Vlad
