Cross correlation of errors

AS test - RS test AS test - RS test
E (A) + E (C) - E (A)E (B) - E (C)
“grasping”“akinesia”
Controls r = 0.7*** r= 0.07
Patients  r = 0.6** r = 0.43-150

  • ↵3-150 P=0.07; **P<0.005; *** P<0.001.

  • E(A)=error A; E(B)=error B; E(C)=error C; R=correlation coefficient.
