Summary
docs/statistics/cuped.mdto distinguish covariates (pre-experiment predictors) from outcome metrics (metrics whose lift estimates CUPED adjusts).Context: customer support thread where a user compared CUPED on GMV7d (time-windowed, aging subject filter) vs unbounded GMV and asked whether excluded covariates are also excluded from result adjustment.
