- Adjustments using estimated response propensities
- Poststratification
- Raking
- General regression estimation
Additionally, the course delves into alternative techniques for imputing values for missing items, ensuring that participants are well-equipped to handle incomplete datasets.
Syllabus Breakdown
The syllabus is structured into several modules, each focusing on different aspects of missing data:
1. General Steps in Weighting
This module introduces the concept of weights and their importance in expanding a sample to represent a population. It covers how to correct for coverage errors, adjust for nonresponse, and reduce variances of estimators.
2. Specific Steps
Here, participants learn the specific steps involved in weighting, including computing base weights and calibrating the sample to external population controls.
3. Implementing the Steps
This module emphasizes the use of statistical software, particularly R, to implement the weighting steps. Participants will explore various R packages that facilitate sample selection and weight computation.
4. Imputing for Missing Items
This crucial module addresses the issue of missing items in surveys. It discusses methods for imputing missing data and how to reflect the effects of imputations on standard errors.
5. Summary of Course
The final module provides a concise summary of the methods covered throughout the course, reinforcing the key concepts learned.
