Table 5 Estimation results for the two-compartment model parameters K 1 , k 2 , k 3 , and k 4 with noise level α = 0.4, using different cut-off frequencies and 250 noise realizations
Cut-off frequency index k c | K 1(min -1) | k 2(min -1) | k 3(min -1) | k 4(min -1) | K 1 (k 3 + k 4 ) /(k 2 k 4 ) | K 1 k 3 /(k 2 k 4 ) | k 3 /k 4 |
