(A and C) Bias in estimated parameters as compared to known parameter values for (A) γ and (B) κ . (C and D) Error in estimated parameters using Hessian method for (C) γ and (D) κ . Fixing γ reduces the bias and error in κ at high corner frequencies by removing parameter correlations. Each point represents the median of 1000 simulations; each simulation contained 4096 bead positions with a constant drag coefficient, γ = 1 × 10 −5 ps/N, and sampling frequency, f s = 100 Hz. The corner frequency was varied logarithmically between 0.2 Hz to 100 Hz. The blue and green points represent two-parameter AV and PSD method fit results. The orange and red points represent fixed gamma AV and PSD method fit results. In the bias plots, the magenta box represents the ±1% bias region. |
