Crosstabulation
Tables Results - Advanced Tab
Crosstabulation
and Stub-and-Banner Tables
Select the Advanced
tab of the Crosstabulation
Tables Results dialog box to access the options described here.
These options provide a greater variety of results (spreadsheets and graphs)
than the Quick tab.
Summary:
Review summary tables. Click the Summary:
Review summary tables button to produce summary tables for multi-way
crosstabulation tables. If more than one table was specified, the Select the tables you want to review dialog
box will be displayed, where you can select the table(s) to be displayed.
The summary crosstabulation table will report the frequencies for the
entire respective table; the last variable (factor) that makes up the
table will be tabulated in the columns of the spreadsheet and all remaining
variables (factors) will be tabulated in the rows. If there are more than
two variables (factors) in a table, the structure of the table will be
as if several two-way tables (for the last two factors) were "glued"
together one-after-another for the different levels of the remaining factors.
In this manner even 6-way tables can be reviewed in a single spreadsheet.
The detail of results that are reported depends on the selections of options
in the Compute tables group box
(Options
tab). Note that, if Expected frequencies
or Residual frequencies are requested,
then they will be computed simultaneously for the entire multi-way table,
via iterative proportional fitting (e.g., see Haberman, 1972, 1974; see
also the Log-Linear
Analysis module). Specifically, expected frequencies are computed
contingent upon the single-factor marginal tables; that is, it is assumed
that there are no interactions
between factors in the table. For three- or higher-way tables these values
will be different from those that are displayed when Detailed
two-way tables are requested, where the expected frequencies are
computed based on the respective two-way tables alone.
Detailed
two-way tables. Click the Detailed
two-way tables button to produce spreadsheets with two-way tables.
If more than one table was specified, the Select the tables you want to review dialog
box will be displayed, where you can select the table(s) to be displayed.
For tables with more than two variables (factors), a cascade of spreadsheets
will be produced for the last two factors in the table, within the levels
of the other factors. The detail of reported results depends on the choices
of options in the Statistics for two-way
tables group box as well as the Compute
tables group box (see the Options tab). If any Statistics
for two-way tables are selected, a spreadsheet with requested statistics
will be computed for each two-way table.
Display
long text labels. Select the Display
long text labels check box to display the long text labels (entered
in the Description field in the
Text Labels Editor) in the first column
of the results spreadsheets that are displayed when the Detailed
two-way tables button is clicked. If the respective variable (factor)
tabulated in the rows of a spreadsheet does not have any long text labels
(none were specified in the Text Labels
Editor), the setting of this check box will be ignored.
Include
missing data. Select the Include
missing data check box to add an extra category (level) for missing
data to each variable (factor) in the table. Thus the table will show
the number of missing cases crosstabulated with the other variables (factors),
and all marginal frequencies and percentages will be adjusted accordingly.
Display
selected %'s in sep.
tables. Select the Display
selected %'s in sep. tables
check box to display the percentage tables in separate spreadsheets (this
is desirable when you want to produce graphs of percentages from the spreadsheets).
Note that this check box is only available (active) if one of the Percentages... options is selected
in the Compute tables group box
(see the Options
tab). By default, this check box is not selected and if percentages
are specified, they will be displayed in the same table together with
the frequencies; thus, each cell in such results spreadsheets will consist
of more than one line.
Categorized
histograms. Click the Categorized
histograms button to produce categorized
histograms for selected tables. If more than one table was specified,
the Select
the tables you want to review dialog box will be displayed, which
is used to select the table(s) for the plot(s). Note that each plot can
summarize up to three variables (factors); that is, one categorized histogram
can summarize a three-way table: The last (fastest changing) factor will
be represented by the columns in the graph; the next-to-last factor will
be represented by the different histograms "tabulated" horizontally;
the third factor will be represented by the different histograms "tabulated"
vertically. Cascades of categorized histograms are produced for tables
with more than three factors.
Interaction
plot of frequencies. Click the Interaction
plot of frequencies button to produce interaction plot(s) for the
selected table(s). If more than one table was specified, the Select the tables you want to review dialog
box will be displayed, where you can select the table(s) for the plot(s).
A line graph (interaction plot) is another way of summarizing the distribution
of frequencies across up to three variables (factors). (If there are more
than three factors in the respective table, a cascade of interaction plots
will be produced for each combination of levels of the remaining factors.)
In each graph, the last (fastest changing) factor will be represented
by different line patterns and colors; the next-to-last factor will be
represented by "upper-x" labels; the last factor will be represented
by "lower-x" labels.
3D histograms. Click the 3D
histograms button to produce 3D
histograms for selected tables. If more than one table was specified,
the Select
the tables you want to review dialog box will be displayed, where
you can select the table(s) for the plot(s). Each 3D histogram will summarize
the joint frequency distribution for two variables (factors); it is in
a sense the graphical equivalent to the Detailed
two-way tables option (see above).
