A framework for causal inference in the presence of extreme inverse probability weights: the role of overlap weights

  title={A framework for causal inference in the presence of extreme inverse probability weights: the role of overlap weights},
  author={Roland A. Matsouaka and Yunji Zhou},
  journal={arXiv: Methodology},
In this paper, we consider recent progress in estimating the average treatment effect when extreme inverse probability weights are present and focus on methods that account for a possible violation of the positivity assumption. These methods aim at estimating the treatment effect on the subpopulation of patients for whom there is a clinical equipoise. We propose a systematic approach to determine their related causal estimands and develop new insights into the properties of the weights…

Practical recommendations on double score matching for estimating causal effects
DSM is doubly robust in the sense that the matching estimator is consistent requiring either the propensity score model or the prognostic score model is correctly specified, and this study supports that DSM performs favorably with, if not better than, the two single score matching in terms of bias and variance.


On adaptive propensity score truncation in causal inference
Results show that by adaptively truncating the estimated PS with a more targeted objective function, the Positivity-C-TMLE estimator achieves the best performance for both point estimation and confidence interval coverage among all estimators considered.
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.
Practice of causal inference with the propensity of being zero or one: assessing the effect of arbitrary cutoffs of propensity scores.
A tree-based method is proposed that performs well in terms of bias reduction when the definition of positivity is based on a single confounder and can be easily implemented using the statistical software program, R.
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.
Causal Inference for Statistics, Social, and Biomedical Sciences: A General Method for Estimating Sampling Variances for Standard Estimators for Average Causal Effects
INTRODUCTION In Chapters 17 and 18, two general frequentist approaches for estimating causal effects were discussed, with special focus on estimating average causal effects. In order to conduct
Average causal effects from nonrandomized studies: a practical guide and simulated example.
In this article, the authors review Rubin's definition of an average causal effect (ACE) as the average difference between potential outcomes under different treatments and review 9 strategies for estimating ACEs on the basis of regression, propensity scores, and doubly robust methods.
Estimation of Regression Coefficients When Some Regressors are not Always Observed
Abstract In applied problems it is common to specify a model for the conditional mean of a response given a set of regressors. A subset of the regressors may be missing for some study subjects either
Flexible regression approach to propensity score analysis and its relationship with matching and weighting
It is shown that the proposed analytical framework can shed light on the intrinsic connection among some mainstream propensity score approaches (stratification, regression, kernel matching, and inverse probability weighting) and handle commonly used causal estimands.
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.
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.
