Fig. 9From: Structural identifiability of cyclic graphical models of biological networks with latent variablesIdentifiability analysis of the influenza A virus replication module. The read nodes are unobserved variables and the green nodes are observed variables in both a and b. In b, the globally identifiable edge coefficients are in green, the locally identifiable coefficients are in blue, and the unidentifiable coefficients are in redBack to article page
