Hi all!
I'm using ROC analysis and would need to calculate whether a certain area under the ROC curve differs from 0.50 significantly. Here is what I think I should get out: http://www.cmh.edu/stats/ask/roc.asp (first table, "asymptotic significance"), but since I'm not primarily using SPSS (I'm using Matlab), I should find another way to get the significance. Which one of the references explains how to calculate the significance (I couldn't find the right one..)?
Also, is there any point in seeing if the 0.50 is included in the confidence interval (between the lower and higher confidence bound? Has anyone used this approach?
Thank you in advance.
Best Regards, Tikkuhirvio
