Multiple comparisons not working in new nonparametric tests

Technote (troubleshooting)


Problem(Abstract)

I used the new Nonparametric Tests procedure (NPTESTS command) to run the Kruskal-Wallis and Friedman tests. I also requested multiple comparisons as part of these analyses. I do not see any output for the multiple comparisons in the Nonparametrics Tests output, but I do not see any warnings or error messages. Where can I find the multiple comparison output?

Resolving the problem

Note that you need to double-click the "Hypothesis Test Summary" table to open the Model Viewer to see further results. At the bottom border of the right panel of the Model Viewer, you will see a scroll bar titled "View". Use the scroll bar to choose "Pairwise Comparisons" and you will see the comparison tests and supporting graphics. There is a Print icon at the top border of the Model Viewer to print these results. Note that in order to have the option for Pairwise Comparisons available, you must select a dependent variable with a significant overall or omnibus test result.


You can find help on navigating viewers in Help->Contents. For a general tutorial on model viewers, Expand the "Core System" , then Scroll down to "Models" and expand that topic. You can find sections on "Interacting with a model" and "Working with the model viewer". For help on the viewer for NPTESTS, expand the "Statistics Base Option" topic and then the "Nonparametric Statistics" topic. Then open the topic "Model View (Nonparametric Statistics)".
You can print all of the Views in the Model Viewer at once, but you can't yet display all of the Model Views at once on the Statistics Viewer, i.e. output window. To print all views, open the File Menu in a Model Viewer, then Properties, and then choose "Print all views". An enhancement request has been filed to to have all views in the Model Viewer displayed in the Statistics Viewer.
