Your formula is only a trapzoidal approximation to the theoretical AUC. It might be downward biased. I am also wondering if there is a funcion in R that can compute the MLE estimate for AUC.
Kerry I agree with you. But I dont Know compute the MLE estimate for AUC and its standatr error.
Second I dont know MLE(AUC)/SE is normal so I dont konw wich test use.
Third I dont konw compute the correction is necessary because the test in same population.
If You explain me this topics I upgrade the funciotn with pleasure.
But same with a possible downward bias the function solve Roman problem...
Thanks in advance
