I am using SPSS v24.0, have run binary logistic regression and multilevel binary logistic regression (genlinmixed) models, saved predicted probabilities from models I want to compare, and run ROC Curve analysis using the predicted probabilities. I’m working with an extremely large dataset, but the analysis runs perfectly well (if a bit slowly) — however, the ROC curve graphs display as ‘Processing…’ and then never show up. I’ve left this sitting overnight in case the graphs are just loading slowly, but no luck.
Even more strangely, now other graphs that used to display properly seem to be showing the same problem (e.g. graphs for specific effects at the end of a multilevel analysis output from genlinmixed syntax).
Note: I have not changed any settings since before this problem appeared, nothing new has happened with/to my desktop computer, and the only new factor is that I hadn’t run the ROC Curve command before.
