Table 1.

Estimated fractions of alternatives ($1-\widehat{afdr}$) for the 17 atoms resulting from 10 KEGG sets, using data from Sotiriou et al. (2006). Each column represents an atom and each row represents a set, with an “X” specifying whether an atom is part of a set. The highest $1-\widehat{afdr}$ is for atom 4, which represents a three-way intersection of the Wnt signaling pathway, the cell cycle, and ubiquitin mediated proteolysis.
