30 Aug 2019: Write f̂(k)(x) =k. 2(n1)ρ(k)(x)for the k-nearest neighbour density estimator at x. ... the Nadaraya–Watson (local constant)estimator m̂(x).

estimator we do not condition on them and instead derive the unconditional distribution. ... A natural estimator for m() at the design point (t,x) is the Nadaraya-Watson (or locally constant).
