The estimation results and variations of MPs corresponding to different given fluctuations of the IPs. (a) The variations in the estimation of parameter E. (b) The variations in the estimation of parameter c. (c) The variations in the estimation of parameter φ (10.65, 4.58, and 46.99 in Figures 15(a)15(c) are the estimation results of the MPs at the reference value of the IPs).
