Table 1. Each column contains the value of the goodness of fit for the three kinematic parameters evaluated using the ARX model.

	Trained on Small, Tested on Large	Trained on Large, Tested on Small	Trained on 80%, Tested on 20%
R2 of Lateral Speed	0.74	0.71	0.67 ± 0.05
R2 of Axial Speed	0.52	0.77	0.79 ± 0.1
R2 of Yaw Speed	0.72	0.71	0.72 ± 0.04

For the last column, the dataset was split randomly in a train and test dataset containing respectively 80% and 20% of the tail bouts. The goodness of fit was evaluated on the test dataset. This procedure was iterated 100 times leading to an estimate of the mean and the standard deviation for the goodness of fit.
