Complete SAS Programming Guide - Learn SAS and Become a Data Ninja - 3 Phase Multiple Imputation Process Using SAS

The video tutorial explains multiple imputation, a method for handling missing data, highlighting its effectiveness over other methods like single and mean imputation. It covers the mechanisms and patterns of missing data, emphasizing the MAR assumption. The tutorial demonstrates a three-phase process using SAS code: imputation, analysis, and combining estimates, providing detailed instructions for each phase.
