Propensity score weighting methods are often used in non-randomized studies to adjust for confounding and assess treatment effects. The most popular among them, the inverse probability weighting, assigns weights that are proportional to the inverse of the conditional probability of a specific treatment assignment, given observed covariates. A key requirement for inverse probability weighting estimation is the positivity assumption, i.e. the propensity score must be bounded away from 0 and 1. In… 

PSweight: An R Package for Propensity Score Weighting Analysis

Propensity score weighting is an important tool for causal inference and comparative effectiveness research. Besides the inverse probability of treatment weights (IPW), recent development has

A regression discontinuity design for ordinal running variables: Evaluating central bank purchases of corporate bonds

Regression discontinuity (RD) is a widely used quasi-experimental design for causal inference. In the standard RD, the assignment to treatment is determined by a continuous pretreatment variable

Variance estimation for the average treatment effects on the treated and on the controls

Common causal estimands include the average treatment effect (ATE), the average treatment effect of the treated (ATT), and the average treatment effect on the controls (ATC). Using augmented inverse

Propensity Score Weighting in R : A Vignette

Propensity score weighting is an important tool for causal inference and comparative effectiveness research. Besides the inverse probability of treatment weights (IPW), recent development has

Model misspecification and bias for inverse probability weighting estimators of average causal effects.

Commonly used semiparametric estimators of causal effects specify parametric models for the propensity score (PS) and the conditional outcome. An example is an augmented inverse probability weighting

Health status balancing weights for estimation of health care disparities

This article presents the balancing weights based on the health status PS applied to the IOM definition of racial disparity and proposes a data-adaptive selection of the tuning parameter for the hybrid weights to minimize the bias of disparity estimates due to the alterations of the distributions of socioeconomic status variables by weighting.

We used Monte Carlo simulations to compare the performance of asymptotic variance estimators to that of the bootstrap when estimating standard errors of differences in means, risk differences, and



Addressing Extreme Propensity Scores via the Overlap Weights

Simulations are used to compare overlap weights to standard inverse probability weighting with trimming, in terms of bias, variance, and 95% confidence interval coverage, and provide a consistent estimator for the standard error of the treatment effect estimated using overlap weighting.

Propensity score weighting analysis and treatment effect discovery

This work develops analytical variance estimates that properly adjust for the sampling variability of the estimated propensity scores, and augment the modified inverse probability weighting estimator with outcome models for improved efficiency, a property that resembles double robustness.

Propensity Score Weighting for Causal Inference with Multi-valued Treatments

This article proposes a unified framework, the balancing weights, for estimating causal effects with multi-valued treatments using propensity score weighting. These weights incorporate the

Balancing Covariates via Propensity Score Weighting

ABSTRACT Covariate balance is crucial for unconfounded descriptive or causal comparisons. However, lack of balance is common in observational studies. This article considers weighting strategies for

Constructing inverse probability weights for marginal structural models.

The authors describe possible tradeoffs that an epidemiologist may encounter when attempting to make inferences and weight truncation is presented as an informal and easily implemented method to deal with these tradeoffs.

The central role of the propensity score in observational studies for causal effects

Abstract : The results of observational studies are often disputed because of nonrandom treatment assignment. For example, patients at greater risk may be overrepresented in some treatment group.

Weight Trimming and Propensity Score Weighting

Although trimming can improve inferences in some settings, in order to consistently improve the performance of propensity score weighting, analysts should focus on the procedures leading to the generation of weights rather than relying on ad-hoc methods such as weight trimmed.

The propensity score is a balancing score: conditional on the propensity score, the distribution of observed baseline covariates will be similar between treated and untreated subjects, and different causal average treatment effects and their relationship with propensity score analyses are described.

Efficient Estimation of Average Treatment Effects Using the Estimated Propensity Score

It is shown that weighting with the inverse of a nonparametric estimate of the propensity Score, rather than the true propensity score, leads to efficient estimates of the various average treatment effects, whether the pre-treatment variables have discrete or continuous distributions.

Demystifying Double Robustness: A Comparison of Alternative Strategies for Estimating a Population Mean from Incomplete Data

When outcomes are missing for reasons beyond an investigator's control, there are two different ways to adjust a parameter estimate for covariates that may be related both to the outcome and to
