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.

Very Respectfully,
