Indeed, 

where ˜ w = αw for some 0 ≤ α ≤ 1 and since h$_{i}$ ≤ ¯ h and | w | < 1 on support of K

holds and the right-hand side is uniformly bounded by some B$_{ψ}$$_{s}$ < ∞ since ψ$_{s}$ ∈ D$_{l}$$_{+}$$_{k}$ ( U ) . Thus 

Similarly, | R$_{2}$ | < ∞ . 

Combining we get that T$_{jj}$ = cov ( ψ$_{1}$, ψ$_{2}$ ) + O ( ¯ h ) as ¯ h → 0 . 

Consider now

Note that here η$_{nhj}$ = n 1 2 ( e$_{nhj}$ − Bias ( ˆ f ) ) . This generalized random function
