On Variance of the Treatment Effect in the Treated When Estimated by Inverse Probability Weighting.
Reifeis SA, Hudgens MG. Reifeis SA, et al. Am J Epidemiol. 2022 May 20;191(6):1092-1097. doi: 10.1093/aje/kwac014. Am J Epidemiol. 2022. PMID: 35106534 Free PMC article.
Here we show that using such an approach when estimating the variance of the IPW ATT estimator does not necessarily result in conservative SE estimates. ...Instead, stacked estimating equations which account for the weight estimation can be used …

Imperfect Synthetic Controls.
Powell D. Powell D. J Appl Econ (Chichester Engl). 2026 Jan 14:10.1002/jae.70035. doi: 10.1002/jae.70035. Online ahead of print. J Appl Econ (Chichester Engl). 2026. PMID: 41608589 Free PMC article.
I also introduce a weighting metric which asymptotically excludes units without appropriate synthetic controls. The paper exploits the estimator's construction of multiple estimates of the treatment effect to produce valid inference even when the number of co …

Demystifying estimands in cluster-randomised trials.
Kahan BC, Blette BS, Harhay MO, Halpern SD, Jairath V, Copas A, Li F. Kahan BC, et al. Stat Methods Med Res. 2024 Jul;33(7):1211-1232. doi: 10.1177/09622802241254197. Epub 2024 May 23. Stat Methods Med Res. 2024. PMID: 38780480 Free PMC article.
In this paper, we provide formal definitions of estimands encompassing both these attributes using potential outcomes notation and describe differences between them. We then provide an overview of estimators for each estimand, describe their assumptions, and show consisten …

Maximum likelihood estimators for colony-forming units.
Martini KM, Boddu SS, Nemenman I, Vega NM. Martini KM, et al. Microbiol Spectr. 2024 Sep 3;12(9):e0394623. doi: 10.1128/spectrum.03946-23. Epub 2024 Jul 23. Microbiol Spectr. 2024. PMID: 39041814 Free PMC article. Review.
We provide an online calculator for these estimators.Estimation of the number of microbes in a sample is an important problem with a long history. ...This mapping enables higher precision estimates of colony-forming units (CFUs) using the same data already co …

Improving trial generalizability using observational studies.
Lee D, Yang S, Dong L, Wang X, Zeng D, Cai J. Lee D, et al. Biometrics. 2023 Jun;79(2):1213-1225. doi: 10.1111/biom.13609. Epub 2022 Jan 11. Biometrics. 2023. PMID: 34862966 Free PMC article.
Complementary features of randomized controlled trials (RCTs) and observational studies (OSs) can be used jointly to estimate the average treatment effect of a target population. We propose a calibration weighting estimator that enforces the covariate balance betwee …

A Comparison of Variance Estimators for Logistic Regression Models Estimated Using Generalized Estimating Equations (GEE) in the Context of Observational Health Services Research.
Austin PC. Austin PC. Stat Med. 2024 Dec 20;43(29):5548-5561. doi: 10.1002/sim.10260. Epub 2024 Oct 31. Stat Med. 2024. PMID: 39478681 Free PMC article.

We suggest that when estimating standard errors: (i) when the number of clusters is < 15 use the Kauermann-Carroll estimator; (ii) when the number of clusters is between 15 and 40 use the Fay-Graubard estimator; (iii) when the number of clusters exceeds 40

Causal Isotonic Regression.
Westling T, Gilbert P, Carone M. Westling T, et al. J R Stat Soc Series B Stat Methodol. 2020 Jul;82(3):719-747. doi: 10.1111/rssb.12372. Epub 2020 May 13. J R Stat Soc Series B Stat Methodol. 2020. PMID: 33986625 Free PMC article.
Nonparametric estimation in this context is challenging because in a nonparametric model these curves cannot be estimated at regular rates. ...In this work, we propose a nonparametric estimator of a causal dose-response curve known to be monotone. We show tha …

Estimating information in time-varying signals.
Cepeda-Humerez SA, Ruess J, Tkačik G. Cepeda-Humerez SA, et al. PLoS Comput Biol. 2019 Sep 3;15(9):e1007290. doi: 10.1371/journal.pcbi.1007290. eCollection 2019 Sep. PLoS Comput Biol. 2019. PMID: 31479447 Free PMC article.
A pressing data-analysis challenge has thus been to efficiently estimate the amount of information that these dynamics convey from experimental data. Here we develop and evaluate decoding-based estimation methods to lower bound the mutual information about a finite …

Proximal Causal Inference without Uniqueness Assumptions.
Zhang J, Li W, Miao W, Tchetgen ET. Zhang J, et al. Stat Probab Lett. 2023 Jul;198:109836. doi: 10.1016/j.spl.2023.109836. Epub 2023 Mar 21. Stat Probab Lett. 2023. PMID: 38405420 Free PMC article.
Solutions to the integral equations may not be unique, which complicates estimation and inference. We construct a consistent estimator for the solution set for one of the integral equations and then adapt the theory of extremum estimators to find from the …

Practical issues in using generalized estimating equations for inference on transitions in longitudinal data: What is being estimated?
Bible J, Albert PS, Simons-Morton BG, Liu D. Bible J, et al. Stat Med. 2019 Mar 15;38(6):903-916. doi: 10.1002/sim.8014. Epub 2018 Nov 8. Stat Med. 2019. PMID: 30411379
Generalized estimating equations (GEEs) are commonly used to estimate transition models. When the Markov assumption does not hold but first-order transition probabilities are still of interest, the transition inference is sensitive to the choice of working correlati …
