We plotted the individual and summary estimates of sensitivity and specificity for each symptom and sign at the different threshold levels in a receiver operating characteristic graph, plotting a symptom's sensitivity (true positive) on the y axis against 1-specificity (false negative) on the x axis.
Using a rank-score characteristic graph to measure the scoring diversity [ 34], combinatorial fusion has been an active research area in the past ten years in a variety of application domains such as microarray gene expression analysis [ 35], motif finding [ 36], protein structure prediction [ 37], virtual screening [ 38], information retrieval [ 39, 33], and target tracking [ 40].
To graphically present the results, we plotted the individual and summary points of sensitivity and specificity in a receiver operating characteristic graph, plotting the index test's sensitivity (true positive rate) on the y axis against 1-specificity (false negative rate) on the x axis.
A receiver operating characteristic graph, with the y-axis representing the index test's sensitivity (true positive rate) and the x-axis representing 1-specificity (false negative rate), was used to plot the individual and summary points of sensitivity and specificity.
[25] Ap-connected graph is separable if and only if its characteristic graph is a split graph.
The sensitivity and specificity of the studies were plotted in a hierarchical summary receiver operating characteristic graph (SROC, Figure 4).
Figure 4 presents the diagnostic values of the studies in a hierarchical summary receiver operating characteristic graph for adults and for children and teenagers.
First we show that in order to find an optimal clique-colouration of a graph, it is enough to have an optimal clique-colouration of its characteristic graph.
The graph G′ obtained from G by shrinking every maximal non-trivial module to a single vertex is called the characteristic graph of G.
Let G be a graph and let G′ be its characteristic graph.
The characteristic graph of G is a complete graph that is 2-clique colourable.
