SAS Tutorial | Missing value imputation using SAS

What is missing value imputation and how do you do it? In this SAS How To Tutorial, SAS’ Jeff Thompson explains why you may encounter missing values (“missingness”) and three ways to impute a missing value:
1) Plug in a summary statistic
2) Use a distributional method
3) Build a model using variables that don’t have missing information to predict the variable that is missing
He then walks through a few pipeline examples to impute missing values in SAS Model Studio.
