In the statistical analysis of observational data, propensity score matching (PSM) is a statistical matching technique that attempts to estimate the effect of a treatment, policy, or other intervention by accounting for the covariates that predict receiving the treatment.
[1] [2] [3] Propensity score matching, an early matching technique, was developed as part of the Rubin causal model, [4] but has been shown to increase model dependence, bias, inefficiency, and power and is no longer recommended compared to other matching methods. [5]
This analysis is called 1:1 propensity score matching (PSM). At baseline, demographic information, including age, sex and education level, was collected. Participants’ cognitive function was ...
This is the case for the example of college attendance: people are not randomly assigned to attend college. Rather, people may choose to attend college based on their financial situation, parents' education, and so on. Many statistical methods have been developed for causal inference, such as propensity score matching. These methods attempt to ...
The estimated propensity score equation is available upon request.) The matched sample is then weighted using propensity score deciles, as described in Ansolabehere and Rivers (2013). The method of inviting respondents means that invitations are shared by multiple studies, so it is impossible to identify a participation rate for individual studies.

Covariate adjustment can be carried out in a variety of ways. Gordon et al. (2018) illustrate many of these methods by means of online advertising data, such as propensity score matching, stratification, regression adjustment, and inverse probability weighted regression adjustment. They find that despite great variation in variables within ...
Polling from Gallup suggests men, white people, college graduates, and higher-income people are among those with a higher propensity to drink. And heavy drinkers consume the bulk of alcohol volume ...
