Webb31 okt. 2024 · Imbens ( 2000) and Hirano and Imbens ( 2004) call this assumption weak unconfoundedness. In contrast, the strong version of unconfoundedness says A i ⊥ ⊥ ( Y i ( a)) a ∈ A X i, which requires all possible potential outcomes ( Y i ( a)) a ∈ A be jointly independent of the causes A i.

Webb1 apr. 2013 · For instance, Hirano and Imbens (2004) show that this works well with continuous treatments when utilizing the residuals from an estimated continuous-treatment-generating econometric model to generate a generalized propensity score which assumes normality and is used in a flexible (e.g., polynomial) functional form as a control function … Webbregimes has been discussed elsewhere (e.g. Imbens, 2000; Hirano and Imbens, 2004; Imai and van Dyk, 2004). Each unit can potentially be assigned to a treatment w, with w= 1 for an active treatment and w= 0 for control. Let W i be the binary variable indicating whether unit iis assigned to the treatment (W i = 1) or to the control (W i = 0).

Webbi(see Hirano and Imbens (2004), Imbens (2000)). This procedure consists of two separate ’prediction’ steps, and machine learning al-gorithms are likely to perform better than the older methods used in the literature. The rst step is the estimation of the conditional probability density of the treatment given the covariates, f TjX(tjx).

The idea is to fit a parametric observable (outcome) model, which includes the estimated GPS as a covariate, to impute missing potential outcomes. The method requires several steps.
