confidence interval for my results. Please help."

-lroc- after -logistic- calculates the AUC, but does 
not display the confidence interval. You may, however,
do this to obtain the confidence interval:

  logistic outcome ...
  predict prob if e(sample)
  roctab outcome prob , summary
 
Is this what you were looking for?
