1. How to compute AUC for Isoproterenol data.
In order to compute AUC, data set need to be restructure to a horizontal format. Use 11.2.isoproterenol.sav for this operation.
Use Compute dialog box, or use Syntax, create the following 6 variables:
COMPUTE auc1 = mean(fbf000, fbf010) * 10 .
COMPUTE auc2 = mean(fbf010, fbf020) * 10 .
COMPUTE auc3 = mean(fbf020, fbf060) * 40 .
COMPUTE auc4 = mean(fbf060, fbf150) * 90 .
COMPUTE auc5 = mean(fbf150, fbf300) * 150 .
COMPUTE auc6 = mean(fbf300, fbf400) * 100 .
COMPUTE AUC= auc1+auc2+auc3+auc4+auc5+auc6 .
EXECUTE .
