| Subject | st: roc with three samples |
| Date | Fri, 1 Nov 2013 10:36:28 -0400 |
I am interested to compare ROC AUC estimates across three samples. I have tried several iterations of the syntax below alternating the inclusion and placement of "clear." I continue to receive this error message: "no; data in memory would be lost." Are there any suggestions for what I am doing wrong with the syntax? Thank you in advance of any suggestions.
