Analysis of the parameter . The figure shows the value of the statistical significance of the main effect in MANOVA analysis for the factor “patient groups.” Logarithmic scale is used. Building PCA using gives different results compared to using or 4. In the case of and 4, the difference between patient groups is strongly significant in the range of 0.1–1.5 Hz which is not observed for . In the range  Hz, the significance is increasing for all , 3, and 4 up to  Hz.
