Now that we understand what cutoff values tell us, let’s look at the three classification methods Prism offers. Area under the ROC curve

Webb6 feb. 2014 · The plot shows the default probability cut off value of 50%. The sensitivity and specificity values associated with this point indicate that performance is not that good when an actual call needs to be made on a sample. One of the most common ways to deal with this is to determine an alternate probability cut off using the ROC curve.

Cutoff Rate and Probability Table. DM algorithms classify via a two-step process. First, the algorithm estimates the probability of belonging to the class of interest. Next, it compares that computed probability to the cutoff value, and classifies the instance accordingly. If the probability meets or exceeds the cutoff value, it assigns it ...
