“…−→ denotes the almost sure convergence; if R ⊂ R d , 13 for some d ∈ N, then intR denotes the interior of R and I(R) denotes the indicator function of the set R; if x ∈ R d , then 14 ∥x∥ denotes the Euclidean norm; L p (R d , w) = {ς : R d → R, |ς (x)| p w(x)dx < ∞}; if ς 1 , ς 2 ∈ L 2 (R d , w) then, 15 ⟨ς 1 , ς 2 ⟩ w = ς 1 (t)ς 2 (t)w(t)dt and ∥ς 1 ∥ 2 w = ⟨ς 1 , ς 1 ⟩ w ; P θ and E θ denote the probability and expectation when the 16 data have cdf F (x; θ ), respectively; P * , E * and var * denote the conditional probability, mean and variance, given the data, 17 respectively; let {A n } be a sequence of random variables and let ϵ ∈ R, then A n = O P (n −ϵ ) means that n ϵ A n is bounded in 18 probability, A n = o P (n −ϵ ) means that n ϵ A n P −→ 0 and A n = o(n −ϵ ) means that n ϵ A n a.s.…”
