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:

>Error # 12581
>A division by zero has been attempted.

By the way here is my entire SPSS code:

 /measure=seuclid.

Get M

 /File='C:\PAMS\Data.sav'

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

Get X

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.
