Dear list!
I got an interesting
solution from Carol Paris. Never thought of “sresid” that way.
Could maybe be of interest to other members of the list.

Staffan,
in the /cells subcommand, add "sresid". This gives you a
standardizsed residual for each cell of your crosstabs table. If a standardized
residual is <-1.96 or >1.96, the frequency of the cell is statistically
greater than or less than expected. It's sometimes helpful to included the
/expected value in the cell also so you can see what the expected frequency is
versus the observed frequency.

Subject: Crosstabulation statistics for a nominal and ordinal variable
Dear list!
I have a crosstabulation problem. I have 2
treatment groups (independent) as the column variable and an ordinal variable
(often, seldom, never) as the row variable. I get a highly significant
chi square using exact test (I got some expected frequencies less than 5).
I, however would like to pinpoint where the main differences lie (within
the ordinal variable) by pairwise comparisons. Besides doing this by creating
new dichotomized variables and performing new analyses on these, is there a
simpler and more economical way of doing this?
