RDU Webinar Series: Use of Imputation Techniques for Modeling Missing Data in Population-based Cancer Registries
Recorded On: 05/20/2016
The purpose of this webinar is to give a global overview of missing data issues and several different imputation techniques. We will also illustrate various applications of imputation techniques in population-based cancer registry settings. We will show improving completeness of biomarkers [e.g., estrogen receptor (ER) status] for breast cancer cases from population-based cancer registries through modeling techniques using standard assumption such as ER status is missing at random (MAR). Additionally, we will demonstrate use of novel imputation methods to perform sensitivity analyses if one suspects ER status is missing not at random (MNAR). The imputed databases are available to researchers for conducting a variety of analyses of breast cancer incidence trends through SEER*Stat software.
