title: How can I get the standard error of an AUC in ROCR?
body: <p>I'm using ROCR to obtain the AUC indices. I want to have also the standard errors of the AUC but in the default outputs they are not shown. Is there any way of obtaining them?</p>
  
  <p>Example:</p>
  
  <pre><code>library(ROCR)
  a&lt;-rnorm(100,1)
  b&lt;-sample(0:1,100,TRUE)
  pred&lt;-prediction(a,b)
  auc&lt;-performance(pred,"auc")
  auc@y.values
  </code></pre>
  
  <p>Thanks in advance for any help!</p>
