330.829.11 SS/R: MISSING DATA PROCEDURES FOR PSYCHOSOCIAL RESEARCH
- Elizabeth Stuart
Since analyses that use just the individuals for whom data is observed can lead to bias and misleading results, students discuss types of missing data, and its implications on analyses. Covers solutions for dealing with both types of missing data. These solutions include weighting approaches for unit non-response and imputation approaches for item non-response. Emphasizes practical implementation of the proposed strategies, including discussion of software to implement imputation approaches. Focuses on recently developed software to implement multiple imputation, such as IVEware for SAS and ICE for Stata. Examples come from school-based prevention research as well as drug abuse and dependence.
After attending this course students will be able to: (1) List the types of missing data, (2) Explain the implications of missing data on study conclusions, (3) Implement the primary strategies for dealing with missing data, including weighting and imputation, and their pros and cons, (4) Implement weighting approaches to deal with attrition, and (5) Implement multiple imputation approaches to deal with general missing data patterns.
