From: Assessing the role of initial conditions in the local structural identifiability of large dynamic models

Figure 2

Identifiability signature of the benchmark model with input (\(M_2\)). (Top) Singular values: When state \(x_1\) is measured and \(x_2(0) = p_1/p_3\), the clear gap between the third and fourth singular values suggests rank deficiency of the sensitivity matrix. (Bottom) Entries in the last column of the right singular matrix: The nonzero entry corresponding to \(p_3\) indicates that parameter \(p_3\) is structurally unidentifiable.
