Motor function in Parkinson's disease and supranuclear palsy: simultaneous factor analysis of a clinical scale in several populations

Table 6 Residual covariances: Common metric completely standardised solution

Residual correlation between	Finger taps			Hand movements			Rapid alternating movements			Leg Agility
	On	Off	PSP	On	Off	PSP	On	Off	PSP	On	Off	PSP
Right and left-hand side	0.13	0.20	0.30	0.11	0.13	0.11	0.09	0.24	0.29	0.16	0.42	0.57

Numbers indicate the residual correlations. For instance, the first number 0.13 indicates the correlation between the residuals of Finger tapping between the right-hand and the left hand for the PD-On-group. All t-values are above 3.
