Unmeasured confounding is often raised as a source of potential bias when evaluating non-randomized study protocols, but evaluating such concerns during their design remains challenging. We propose a flexible methodology based on individual level simulations that can allow researchers to characterize the bias arising from unmeasured confounding with a specified but modifiable structure during the study design.
sim.BA allows user to conduct a simulation-based
quantitative bias analysis using covariate structures generated with
individual-level data to characterize the bias arising from unmeasured
confounding. Users can specify their desired data generating mechanisms
to simulate data and quantitatively summarize findings in an end-to-end
application using this package. See vignette("sim.BA") for
details.
You can install the development version of sim.BA from
GitLab with:
