Cross-Framework Sensitivity Analysis with an OLS Crosswalk

Runs, classifies, interprets and reports sensitivity analyses for unmeasured confounding across the partial R-squared robustness value approach (Cinelli and Hazlett, 2020, ), E-values (VanderWeele and Ding, 2017, ), and the impact threshold for a confounding variable and robustness of inference to replacement (Frank, 2000, ; Frank, Maroulis, Duong and Kelcey, 2013, ). An ordinary least squares crosswalk reports the robustness values, impact threshold and replacement percentage computed from the focal t statistic and residual degrees of freedom, makes explicit that their agreement is largely fixed by that shared input, and flags the boundary band in which they disagree. Template-based plain-language reports are included, with optional integration with the 'confoundvis' package for plots.
