A global response adjustment transfers weight across response cells.

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Case contract

Rows are (cell, positive base weight, responded boolean). Return adjusted respondent weights in row order; return None if any represented cell has zero respondents. Empty input returns empty list.

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 fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
different cell response	`[4.5, 4.5]`	`[6, 3]`	Failed
