Visual representation of Eq. 14. The left and right matrices represent the time evolution of hidden states for the ipsi- and contralateral necks, respectively. The right matrices distinguish between the cases of no midline extension (top) and midline extension (bottom). The central diagonal matrix shows the time-prior for late T-category tumors. This computation yields the joint distribution \(P \left( \mathbf{X}^\text {i}, \mathbf{X}^\text {c}, \epsilon \right)\), visualized in Fig. 6.
