3.2. COP Sway Area
fits
The value of COP-SA is highly skewed and might follow a lognormal distribution, similarly to the COP distance variable (In comparisons made in the EG, the measurement model fits the data slightly better than the null model, which is confirmed by the LOOIC difference of -5. Furthermore, the effect of time measurement accounted for 1% of the variance of the EO dimension and for 0% of the variance of the EC variable (In comparisons of results between groups the model with the interaction effect did not fit the data better than the main effects model, which is confirmed by the KFOLDIC difference of 3, nor did the null model, which is confirmed by the KFOLDIC difference of 3. These results indicate a lack of reliable differences for the COP-SA variable between the groups (
