Exact Global Minimax Risk near Nonidentification
arXiv:2610.32546v1 Announce Type: new Abstract: We study squared-error estimation when a nuisance parameter is unidentified on a submodel but affects a target that vanishes there. For models with higher-order profile expansions, we give sufficient conditions under which the largest critical-path mi…
