Importance weights

Read Original

The article discusses a fourth type of statistical weight beyond sampling, precision, and frequency weights. It focuses on dual-frame survey estimation, where two overlapping samples (e.g., mobile and landline) require adjusted weights to prevent double-counting individuals in the overlap, using examples like health surveys. The technical explanation covers the mathematical formulation for correct point estimation and variance.
