Quantifying Sensitivity to Selection on Unobserved Covariates: Recasting the Coefficient of Proportionality

Joint Statistical Meetings (JSM 2025) — Multi-faceted Approaches to Sensitivity Analysis for Observational Studies
Date: August 6, 2025 (10:30 AM – 12:30 PM CT) | Location: Nashville, TN

  • Presenters: Kenneth A. Frank, Qinyun Lin, & Spiro Maroulis
  • Abstract: Perhaps the most prevalent index used for sensitivity analyses is Oster’s (2019) Coefficient of Proportionality (COP). In this paper, we reconceptualize the COP as a function of unobserved covariates’ correlations with the focal predictor and outcome. Our correlation-based approach addresses recent critiques of Oster’s COP while preserving the comparison of selection on unobserved covariates to selection on observed covariates without depending on an analyst’s subjective choice of baseline model covariates.
