Figure 3.

Initial estimated state bounds. The true state values resulting from x₁(t₀) = x₂ (t₀) = 50 and p = [1, 0.01, 1, 0.02] are shown in grey (x*). The initial measurement set is shown as uncertainty bounds in x₁ at t = 2, 4, and 6 . Recall that measurements are only available for x₁. The dashed lines show the results of the uncertainty propagation of the estimated parameter boxes in Figure 2 (x_est). The dotted lines show the positions of candidate times points (t_j).
