N nx e. Expected value and bias Recall that E ijX i = 0, so 1 n i=1 (x i x )E i = 0 (23) Thus, E h ^ 1 i = 1 (24) Since the bias of an estimator is the di erence between its expected value and the truth, ^ 1 is an unbiased estimator of the optimal slope 4 (To repeat what I’m sure you remember from mathematical statistics \bias".

Then fn(x) = 0 for all n, so fn(x) → 0 also It follows that fn → 0 pointwise on 0,1 This is the case even though maxfn = n → ∞ as n → ∞ Thus, a pointwise convergent sequence of functions need not be bounded, even if it converges to zero Example 55 Define fn R → R by fn(x) = sinnx n Then f n→ 0 pointwise on R.
