Replicate the first four rows. Assume
fˆ is a product kernel estimator. You may find it helpful to begin with the expression MSEh(fˆ(x)) = var{fˆ(x)} + _ bias
fˆ(x) __2, and to use the result
φ(x;
μ, σ2)φ(x;
ν, τ2) =
φ
where
φ(x;
α, β2) denotes a univariate normal density function with mean
α
and variance
β2.
