WebFrom here it's possible to see that an influence function is the Gateaux derivative of ˆθ at F in the direction of δx. This makes the interpretation of influence functions (for me) a little bit clearer: An influence function tells you the effect that a particular observation has on the estimator. The OLS estimate is a solution to the problem: WebThe Gateaux derivative is a general form of directional derivatives in that the change of the function value can be considered along an arbitrary direction. The Gateaux derivative of functionals lifts this concept to functionals (i.e., mappings from functions to real numbers). Intuitively, it is an

WebFor clarity purpose, we may denote by dJ the Fr´echet derivative, and by J0 the Gateaux derivative. Definition 2.1 J : V → H has a directional derivative at point u ∈ V along the direction v ∈ V if lim θ→0+ J(u+θv)−J(u) θ exists, and we denote by J0(u;v) the limit. Example: V = Rn and H = R, partial derivatives of J: J(u+θe i ... Webconnections between this concept of orthogonality, and the Gateaux derivative and the subdifferential set of the norm function are provided… Show more In the last few decades, the concept of Birkhoff-James orthogonality has been used in several applications. In this survey article, the results known on the necessary
WebWe study a constructive procedure that approximates Gateaux derivatives for statistical functionals by finite-differencing, with attention to causal inference functionals. We focus on the case where probability distributions are not known a priori but need also to be estimated from data, leading to empirical Gateaux derivatives, and study relationships between … WebThe Gâteaux differential If y = y (x) is a stationary path of the functional S [y] , and h (x) is any alternative path that satisfies the same boundary conditions, then we write the Gâteaux differential as follows: Δ S [ y, h] = ∂ ∂ ϵ S [ y + ϵ h] ϵ = 0
