Hello,
According to PSPP's automatic messaging, it seems that I have just discovered a bug of PSPP. I was Doing Crosstabs with two qualitative variables and asking for all the reports from the Cell tab, except (clearly) None. I also had Phi and Cramer's V selected in the Statistics tab.
This operation used to work last year on the same database (I am teaching the same course this year and the last). The PSPP version that i have now is the newest. Last year it was the latest one released in 2021.
Let me know if you need more info
Thanks for taking care of it!
Regards
Alexandra
