ROC Curves with Conditional Logistic Regression

deleted_user — Fri, 25 Jul 2008 13:43:14 GMT

Why is it not possible to construct receiver operating characteristic curves when implementing conditional logistic regression?

From a SAS perspective, why is it that we cannot use the 'strata' statement and the 'outroc' option in proc logistic?

Thank you in advance for any insight.

I sure do wish someone would reply to this post. I need to conduct a ROC and would like to do it in logistical regression as well.

Which SAS Proc do you use the 'strata' and 'outroc' options?

Thank you!

Hi,

ROC that you can request in PROC LOGISTIC is based on predicted probabilities, and we do not obtain predicted probabilities with conditional logistic regression.
