Code Co-Occurrences

The Code Co-Occurrences tool allows you to see which codes overlap with each other. Codes make up both the rows and the columns of the table. Each cell counts the number of times the row's code and the column's code occur together.

Two codes occur together when:

• They are applied to the same selection; or,
• They are applied to selections that overlap.

To open Code Co-Occurrences:

1. Click the Analyse button in the toolbar.

2. Choose Code Co-Occurrences.

The tool contains the Document Selector.

Adding codes

To add codes to the table:

1. Drag the codes from the Code Browser into either:

   1. The Drop codes here for rows box, to add them as rows;
   2. The Drop codes here for columns box, to add them as columns; or,
   3. Anywhere else in the Co-Occurrence Grid, to add them as both rows and columns.

2. The table fills in as you add codes.

3. To remove a code, click the x beside its name.

TIP

Dropping the same codes into both the rows and the columns gives you every combination at once. Where a code meets itself, the cell shows a dash: a code always overlaps with itself, so it is not counted.

Reading the results

Each cell shows how many times the two codes occur together. The Total column and row add up the table, and the % of Total column shows each row's total as a percentage of the grand total.

The co-occurrence table, with the same five codes as both rows and columns.

You can change how the results are displayed using the buttons above the table. The first set of buttons chooses how the results are shown, and the second chooses what each cell counts. The highlighted buttons show the current choice.

Button	Output
Table	Shows the results as numbers. This is the default.
Visual	Shows each cell as a coloured square, sized and shaded by its count.
Sankey	Shows the table as a Sankey diagram, linking each row's code to the codes it occurs with.
Counts	Shows how many times the two codes occur together. This is the default.
Binary	Shows 1 if the two codes ever occur together and 0 if they do not. You can use it with Table, Visual or Sankey.

Exploring the results

Click any cell with a count above zero to see where the two codes overlap. The overlapping selections appear in the Query Results pane.

• Clicking a row's Total shows every selection coded with that row's code.
• Clicking a column's Total shows every selection coded with that column's code.

Saving and exporting

You can save the analysis by clicking Save Analysis. It appears in the Analyses Panel. If you make changes later, click Update Analysis to save them.

You can export the table as a spreadsheet by clicking Export CSV.

You can also add the analysis to a Report by dragging it from the Analyses Panel into the report.
