We propose an optimal-transport-based matching method to nonparametrically estimate linear models with independent …

"Matching" is a statistical technique used to evaluate the effect of a treatment by comparing the treated and non …-treated units in an observational study. Matching provides an alternative to older estimation methods, such as ordinary least … remarkable increase in computing power since then has made other methods, in particular matching, very easy to implement. …

Matching estimators are widely used in statistical data analysis. However, the distribution of matching estimators has … matching estimators. This representation allows the use of martingale limit theorems to derive the asymptotic distribution of … matching estimators. As an illustration of the applicability of the theory, we derive the asymptotic distribution of a matching …

selection-on-observables type assumptions using matching or propensity score methods. Much of this literature is highly …

nonparametric matching and weighting estimators of the average treatment effects and their properties are examined. …

This paper compares the inverse-probability-of-selection-weighting estimation principle with the matching principle and … derives conditions for weighting and matching to identify the same and the true distribution, respectively. This comparison …
