Table 3: Statistical pairwise t-tests for difference in apex top response angle, for variations of the models using the basic 5 load-states. Based upon the mean of the variable obtained by subtracting the stochastic variable corresponding to the first type of model, from that corresponding to the second type of model (the Matlab built-in function ’ttest’ was used).

Isotropic models, basic states versus with
additional clockwise shear components
n=25, p-value ≈ 0.73
Isotropic, basic states versus with additional
counter-clockwise shear
n=25, p-value ≈ 0.79
Isotropic, with additional counterclockwise
versus clockwise shear
n=25, p-value ≈ 0.97
Isotropic versus orthotropic models n=25, p-value ≈ 0.084
