Mechanisms¶
- Matched Case Comparison
- A common way to collapse those factors into a single closeness score is propensity-score matching.
This sourceDefines the propensity score as a scalar summary of observed covariates and identifies matched sampling on it as an application.

- Matched Case Pairing Protocol
- Its defining limitation is the flip side of that: it can only balance observed covariates, so an unmeasured difference — the very motivation that made families opt in — rides straight through the match untouched.
This sourceShows that propensity-score matching balances observed covariates but does not remove differences not represented in those covariates.
