Synthetic Data Got a Size-Weight Boundary
A calibrated frontier limits how much weighted synthetic survey data can enter an inference procedure while retaining target coverage.
Summary
A calibrated frontier limits how much weighted synthetic survey data can enter an inference procedure while retaining target coverage.
The framework estimates, from historical tasks, the largest synthetic sample size allowed at each weight and supplies a simultaneous finite-sample coverage guarantee below that boundary. In opinion-survey experiments using language-model responses, the method reached target coverage and narrowed confidence intervals.
Why it matters
A calibrated frontier limits how much weighted synthetic survey data can enter an inference procedure while retaining target coverage.
Limits and context
No additional limitation was separately recorded.
Key claims
