Parameter estimation of the noisy L-63 system using the method with stochastic parameterized Equations (146) and (147) with ${\sigma }_x={\sigma }_y={\sigma }_z=15$. (a–c) sample trajectories of $x,y,z$ which are used as observations; (d–f) time evolution of the estimated parameters and the truth (red); the thin black line shows the average of the estimation from $t=10$ to $t=50$; (g)–(i) the uncertainty evolution of each estimated parameter.
