Can You Trust the Prediction?

Triangulation check

The simulator estimates what happens when one or two factors change, using the published outcome model. The triangulation check estimates the same scenario a second, independent way — a propensity model built live from the same predictors but relying on the outcome much less directly. That independence is the point. When two methods that rest on different assumptions land close, the result is less likely to be an artifact of one modeling choice. When they diverge, read the prediction cautiously; the cause may be a small sample, weak overlap, residual imbalance, or model dependence.

Filter to a subgroup (or stay on All respondents), change one or two factors below, then click Run scenario. The check appears underneath.
