Covariate balancing propensity score
The propensity score plays a central role in a variety of causal inference settings. In particular, matching and weighting methods based on the estimated propensity score have become increasingly common in the analysis of observational data. Despite their popularity and theoretical appeal, the main practical difficulty of these methods is that the propensity score must be estimated. Researchers...
متن کاملHigh Dimensional Propensity Score Estimation via Covariate Balancing
In this paper, we address the problem of estimating the average treatment effect (ATE) and the average treatment effect for the treated (ATT) in observational studies when the number of potential confounders is possibly much greater than the sample size. In particular, we develop a robust method to estimate the propensity score via covariate balancing in high-dimensional settings. Since it is u...
متن کاملCovariate Balancing Propensity Score for General Treatment Regimes
Propensity score matching and inverse-probability weighting are popular methods for causal inference in observational studies. Under the assumption of unconfoundedness, these methods enable researchers to estimate causal effects by balancing observed covariates across different treatment values. While their extensions to general treatment regimes exist, a vast majority of applications have been...
متن کاملVariable selection for propensity score estimation via balancing covariates.
We first define some notation. Let Y denote the response of interest and X denote a p-dimensional vector of covariates. Let T denote a binary indicator of treatment exposure: T = 1 if treated, T = 0 if control. (Yi,Xi, Ti), i = 1, . . . , n, is a random sample from (Y,X, T ). We further define Y (1) as the potential outcome if the subject were treated and Y (0) as the potential outcome if the s...
متن کاملpropensity score analysis
Methods for propensity score analysis (PSA) originated with Rosenbaum and Rubin (1983), as vehicles to sharpen and clarify treatment group comparisons in observational studies. Although highly recommended by many statisticians, and applied often in medical sciences, PSA has seen relatively few applications in the social and behavioral sciences. This paper aims to facilitate sound PSA applicatio...
