Hi everyone,

I'm doing some analysis on diagnostic data using ROC curves using Sigma Plot.
I have 5 variables that are being used to help predict the true diagnosis. I have looked at the accuracy of each of these varable seperatly but now I want to combine a number or all to see if when combined the diagnostic accuracy increases.

Does anyone have any experience in doing a combined analysis like this?
