WebJul 28, 2016 · In my real life example, I obtain very poor accuracy using P > 0.5 as my classifying cutoff (about 51% accuracy). However, when I looked at the AUC it is above 0.99. So I looked at some different cutoff values and found that P > 0.6 gave me 98% accuracy (90% for the smaller class and 99% for the bigger class) - only 2% of cases misclassified. Web1 Answer. The accuracy is likely to go down if you change the cutoff point to 0.9, since any model tries to separate the classes so that the probability of the correct class is higher …
