Sampling
Our extensive sampling capabilities support our work in survey design and other disciplines for which clear targeting of sample populations is a foundation for robust statistical inferences. Our expertise touches every aspect of survey design and analysis, including questionnaire design, sampling of rare populations, and techniques to account for missing data.
Focus Areas
- Sampling frame construction
- Sample design and selection
- Small area estimation
- Rare population sampling: general population screening, list sampling, network sampling
Methodologies/Techniques
- Sample optimization
- Stratification
- Clustering and multistage sampling
- Composite measures of size
- Probability minimum replacement (PMR) sampling
- Controlled selection
- Multiphase (or double) sampling
- Multiple-frame sampling
- Adaptive sampling
Applications
- Census-based area household frames
- List frames for institutions and recipients of Medicare or Medicaid
