Once I transform the data I can't do SNK tests. The message is simply "No test" without more explanation. This error occurred several times. What can I do?
In order to fix the issue, try uninstalling the software (Control Panel > Uninstall a program) and then install it again. Also, before beginning the re-installation process, I recommend you run CCleaner or Glary Utilities to make sure that there are no leftover registry keys in your system.
