Jan 31, 2008 · To begin with, a first decision has to be made concerning the estimation of the propensity score. Following that one has to decide which matching algorithm to choose and determine the region of common support. Subsequently, the matching quality has to be assessed and treatment effects and their standard errors have to be estimated.Cited by: 5163

In case of non-parametric (semi-parametric) estimation (matching on X or on the propensity score) this assumption is crucial. However, I am wondering whether this assumption has to hold if I want to estimate the treatment effect in a parametric regression (e.g. a simple multivariate linear model fitted by OLS).

Propensity score matching Basic mechanics of matching The matching criterion could be as simple as the absolute difference in the propensity score for treated vs. non-treated units. However, when the sampling design oversamples treated units, it has been found that matching on the log odds of the propensity score (p=(1 p)) is a superior criterion.

Rosenbaum and Rubin (1983) proposed propensity score matching as a method to reduce the bias in the estimation of treatment e ects with observational data sets. These methods have become increasingly popular in medical trials and in the evaluation of economic policy interventions. Grilli and Rampichini (UNIFI) Propensity scores BRISTOL JUNE ...

https://en.wikipedia.org/wiki/Propensity_score
Propensity score. A propensity score is the probability of a unit (e.g., person, classroom, school) being assigned to a particular treatment given a set of observed covariates. Propensity scores are used to reduce selection bias by equating groups based on these covariates.
