| Date | Wed, 5 Feb 2014 19:17:31 +0000 |
Dear Statalist, I used estat classification after a logistic regression to find the sensitivity, specificity, and positive predictive value. Using estat classification I get a sensitivity of 0% and a specificity of 100%. However, using roctab I get a sensitivity of 12.5% and specificity of 80%. Does anybody have an idea of what is wrong with the estat classification statement? Thank you for your help.
