Table 1.

RMSE values for the sigmoidal and linear curves fitted for each of the movement directions and ratio conditions simulated by the model

Ratio 25 50 75 100
Approaching
 Sigmoidal 3.52 4.86 6.80 8.04
 Linear 5.60 5.80 5.89 5.80
Receding
 Sigmoidal 2.59 4.58 6.86 8.70
 Linear 0.65 0.65 0.58 0.65

The curve with the lower error RMSE explains the data for that condition better
