Influential Factors of an Asynchronous BCI for Movement Intention Detection

Table 4

Simple effects of frequency with each type of spatial filter from the one-way repeated measures ANOVA test of F1 scores.

Source	Type III sum of squares	Corrected degree of freedom	Mean square	F value	value	Partial eta squared
Freq on NoF	0.058	3.303	0.018	5.536	0.001	0.095
Error (freq on NoF)	0.557	175.053	0.003
Freq on SL	1.602	3.167	0.506	70.402	0.000	0.571
Error (freq on SL)	1.206	167.856	0.007
Freq on ICA	0.196	3.085	0.064	10.265	0.000	0.162
Error (freq on ICA)	1.014	163.490	0.006
Freq on CSP	0.015	2.743	0.005	0.643	0.575	0.012
Error (freq on CSP)	1.196	145.357	0.008
Freq on PCA	0.086	3.433	0.025	6.094	0.000	0.103
Error (freq on PCA)	0.746	181.937	0.004

There are significant simple effects of frequency band on all types of spatial filter but not CSP, where value is more than 0.01.
