WebA graph is a split graph if its vertex set can be partitioned into a clique C and an independent set I, where (C,I) is called a split partition. A threshold graph is a split graph whose vertices can be ordered by neighborhood inclusion [12, 18]. Next we define a partitioning of the vertex set of a threshold graph that is used throughout the paper.
WebEach ROC analysis creates one ROC curve and graph. The XY points that define the graph are on a results page called "ROC curve". You can plot multiple ROC curves on one graph if you want to. The easiest way to do so is to go to a graph of one ROC curve, and drag the "ROC curve" results table from another one onto the graph.
