Table 2.

p-values of the tested approaches using a pairwise Wilcoxon signed rank test and the root mean square error.

Methods	Radar Estimation vs. Approach Estimation			WF vs. WB (p-Value)	Walk and Turn
	WF (p-Value)	WB (p-Value)	B and A Turn (p-Value)		p-Value	RMSE
1st approach	0.0215	0.0061	<0.001	0.0803	<0.001	0.4099
2nd approach	<0.001	<0.001	<0.001	0.1677	<0.001	0.5761
3rd approach	0.0171	0.0024	0.2477	0.6848	0.2083	0.3675

Notes: WF: walk forward; WB: walk back; B and A turn: before and after turn; RMSE: root mean square error.
