Missingness Mechanism

Missingness mechanisms describe how and why data are missing, a crucial consideration in data analysis because ignoring the mechanism can lead to biased results. Current research focuses on developing methods to identify and account for different missingness mechanisms, ranging from simple imputation techniques to sophisticated deep learning models like variational autoencoders and masked autoencoders, and exploring the impact of missingness on causal inference and treatment effect estimation. Understanding and addressing missing data is vital for reliable scientific conclusions and accurate predictions across diverse fields, particularly in healthcare and other areas with inherently incomplete datasets.
