This happens when the selection consists of one single grouping variable. It's been patched now and should reach you with the next Prototypes release.
Thanks!
Awesome, I will be looking forward to this! best regards
can I ask if this widget is designed to perform simple inference between groups? Since it has no documentation.
@bernard-liew Designed to perform inference between groups of values of nominal variables and one Test Variable.
Prototypes version
0.90
Orange version
3.8.0 (git revision:58a5218)
Expected behavior
Prototype "Significant Groups" can perform a variety of statistical tests for Hypothesis Testing (i.e. Student's t-test, Mann-Whitney-U test)
Actual behavior
An exception occurs stating "'DiscreteVariable' object is not iterable"
Steps to reproduce the behavior
I have reproduced this error on several Windows 7 Systems with updated and newly installed versions of Orange Canvas.
Here is an example pipeline: Significant groups issue.ows Hit compute in the "Significant Groups" widget to cause the exception.
