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 >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 >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 >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 # 721

>Error # 12364 >Number of column elements is not the same in constructing the matrix. Number >of elements in one column should be the same for all the columns. >This command not executed.

By the way here is my entire SPSS code:

compute w=solve(m1,m2).

compute tw=transpos(w).

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.
