NMSE (dB) boxplots (upper panel, ac), absolute difference between simulated and estimated PSD (middle panel, df), and time evolution of NMSE (bottom panel, gi) for Scenario I (left panel, a, d, g), II (middle panel, b, e, c), and III (right panel, g, h, i). Blue, red, yellow, and green boxplots/curves refer to direct-form models estimated by KF-RPLS and cascade-form models estimated by KF-RPEM, RB-UKF, and RB-CDKF,respectively
