Part (c)
Let Yit = xh,3,it — EFz xh,3,it. Using the arguments similar to those used in
the proof of Part (b), we can show that under Assumption 4,

for some constant M. By Assumption 4(i), P∞= s2 supi aFZ (s) q < ∞ a.s..
Finally, since the terms supi t kYitkF 4q and PS=1 s2 supi αFz. (s) q are F∞o-
