Re: I need some help

I don't know if PSPP (or SPSS) can do Pareto Diagrams. So, maybe PSPP
isn't the tool you need.

But PSPP has (I think) the same capabilities of combining data as SPSS,
but I think you do need to use syntax. This page describes the commands
to combine data files. There's a command to stack files/add cases (ADD
FILES) and a command to merge files/add variables (MATCH FILES). If you
click on the link for your choice at the bottom, you'll see the syntax.

https://www.gnu.org/software/pspp/manual/html_node/Combining-Data-Files.html#Combining-Data-Files

You would click "New Syntax" and type the commands there and then click
run, but if you describe what you're trying to do, we can give you
additional advice. For example, you'll need to sort on the matching
variable(s).

If I had files 'test1.sav' and 'test2.sav' with matching variable
'index' I would type:

* sort file 1 by match variable.
get /file='test1.sav'.
sort cases by index.
save /outfile'test1.sav'.

* sort file 2 by match variable.
get /file='test2.sav'.
sort cases by index.
save /outfile'test2.sav'.

match files file='test1.sav'
  /file='test2.sav'
  /by index
  /map.
execute.

The number one pain I experience in combining data (using PSS or PSPP)
is when the same variable has a different data type across files. This
is extremely common with string variables. Number two is duplicate
identifiers.
