Figure 6. Comparison of a parsimonious fourth-order HMM to existing methods on the Arabidopsis Array-CGH data set.

Receiver operating characteristic (ROC) curves for comparing the identification of deletions or sequence deviations in the Array-CGH data set. ROC curves are shown for FHMM, ACE, CBS, and GLAD of the ADaCGH webserver [43], segMNT [21], wuHMM [56], GHMM [52], RJaCGH [55] and the parsimonious fourth-order HMM with underlying state-context tree in Figure 5. The parsimonious fourth-order HMM reaches the best identification of deletions and sequence deviations (black).
