An efficient multiple imputation algorithm for control-based and delta-adjusted pattern mixture models using SAS
Yongqiang Tang
In clinical trials, mixed effects models for repeated measures (MMRM) and pattern mixture models (PMM) are often used to analyze longitudinal continuous outcomes. We describe a sim…
