Fig. 1
Variation in MSE of the calibrated mixed models with calibration height for the models shown in Table 2. Two different groups are considered: group 1 (solid lines), expanding the following fixed-effects parameters: a 2, b 2; a 1, b 2; a 0, b 2; a 2, b 0; a 1, b 0; a 0, b 0; a 2, b 3; a 1, b 3; a 0, b 3; b 6; and group 2 (dotted lines), expanding the following fixed-effects parameters: b 0, b 1; b 1, b 3; b 1, b 2; b 2; b 3; b 1, b 4; b 0, b 3; b 0, b 6; b 3, b 4; and b 2, b 3. The MSE of the fixed part of the “a 1, b 0” mixed model (i.e., the mean response: horizontal solid line) and the MSE of Eq. 1 fitted with ONLS and correction for autocorrelation (horizontal dashed line) are also shown
