3.3. COP Sway Velocity
fits
Similarly to COP distance and COP-SA, COP sway velocity is characterized by a noticeable positive skewedness, and lognormal distribution was also used for the analysis of COP sway velocity (In comparisons made in the EG, the measurement model fits the data better than the null model, which is confirmed by the LOOIC difference of −9. Furthermore, the effect of time measurement accounted for 7% of the variance of the EO dimension and for merely 1% of the variance of the EC variable (In comparisons of results between groups, the model with the interaction effect fits better the data better than the main effects model, which is confirmed by the LOOIC difference of −7, or the null model, which is confirmed by the LOOIC difference of −3. Main effects, interaction time and groups accounted for 6% of EO variance and 2% of EC variance (
