“…Specifically, in a shrinking neighborhood of ρ 1/2 n x 0i with radius n , condition (4.2) requires that the negative Hessian of (1/n) in is close to a deterministic d × d positive definite matrix Σ in , and condition (4.3) guarantees that in is strongly concave in a larger shrinking neighborhood of ρ 1/2 n x 0i with radius 3δ n . Finally, condition (4.4) is an identifiability condition for the criterion function, which is standard in the literature on generalized Bayesian estimation (see, for example, Chernozhukov and Hong, 2003;Chib et al, 2018;Yiu et al, 2020;Zhao et al, 2020).…”
