I would like to perform a nonparametric multiple comparisons test from a "Fit Y by X" report. I want to compare the levels of my variable with a given control level. Nevertheless, when I select "Steel with control" the control group is automatically selected and I can't choose it. I have tried to change the "Value ordering" property of my variable but it doesn't change anything.
Do you know how I can precise my control group ?
Thanks in advance for your help!
Thank you for your answer and sorry for the delay.
I ran the analysis several times but it didn't change anything. Finally after closing the data table and re-opening it, I get the selection window!
That is weird indeed but at least I am not the only one who sees that bug!
