Normalizing inclusion weights changes a population total · case 03
Normalizing inclusion weights changes a population total.
Case contract
Rows are (value, positive inclusion probability <= 1); return the estimated population total rounded to eight decimals; empty sample totals zero.
Why this case matters
A deterministic survey-design model isolates this sampling contract before it is embedded in a larger estimation pipeline.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| unequal probabilities | 5.0 | 30 | Failed |
