| Subject | st: Question on ROC analysis |
| Date | Thu, 19 May 2011 14:46:56 -0400 |
I am interested in carrying out a simple two variable ROC analysis. I want to assess how well low values of my x variable predict a low value of my y variable (e.g. y variable with cutoff less than 200). However, if I understand correctly, the conventional ROC analysis in Stata creates the ROC by using incrementally increasing values of x to predict y. How do I adapt the analysis so that the AUC result I obtain will be consistent with the relationship I am interested in quantifying? * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
