How Model-Dependent Is the Estimate?

Triangulation check

The simulator reports what the fitted outcome model implies under a stated scenario. The triangulation check estimates that same scenario through a structurally different observational route — propensity-score subclassification built from the same measured predictors rather than the published outcome model. The two routes differ in form, but they share the sample, measured controls, and important observational limitations. When they land close, one concern narrows: the result appears less dependent on the published logit specification. Agreement is not confirmation of a causal effect, and either estimate may be too imprecise to settle the size. When they diverge, read the result cautiously; possible reasons include small samples, weak overlap, residual imbalance, or model dependence.

Filter to a subgroup (or stay on All respondents), set one or more scenario values below, then click Run scenario. The check appears underneath.
