Propensity Score-matching Methods for Nonexperimental Causal Studies
This paper considers causal inference and sample selection bias in nonexperimental settings in which (i) few units in the nonexperimental comparison group are comparable to the treatment units, and (ii) selecting a subset of comparison units similar to the treatment units is difficult because units must be compared across a high-dimensional set of pretreatment characteristics. We discuss the us...
متن کاملUncertain Neighbors: Bayesian Propensity Score Matching for Causal Inference
In this paper we compare the performance of standard nearest-neighbor propensity score matching with that of an analogous Bayesian propensity score matching procedure. We show that the Bayesian approach has several advantages, including that it makes better use of available information, since it makes less arbitrary decisions about which observations to drop and which ones to keep in the matche...
متن کاملPropensity Score Matching for Causal Inference with Relational Data
Propensity score matching (PSM) is a widely used method for performing causal inference with observational data. PSM requires fully specifying the set of confounding variables of treatment and outcome. In the case of relational data, this set may include nonintuitive relational variables, i.e., variables derived from the relational structure of the data. In this work, we provide an automated me...
متن کاملPropensity Score Methods for Causal Inference with the PSMATCH Procedure
In a randomized study, subjects are randomly assigned to either a treated group or a control group. Random assignment ensures that the distribution of the covariates is the same in both groups and that the treatment effect can be estimated by directly comparing the outcomes for the subjects in the two groups. In contrast, subjects in an observational study are not randomly assigned. In order to...
متن کاملPropensity Score Matching for Multiple Treatments Comparison in Observational Studies
A major limitation of making inference about treatment effect based on observational data from a non-randomized study designs is the treatment selection bias, in which the baseline characteristics of population under one treatment could dramatically differ from the other one. If not handle properly, such sources of heterogeneity will introduce confounding effect into causaleffect relationship a...
