The proportion of missing data should not be used to guide decisions on multiple imputation
Journal of Clinical Epidemiology, 2019 Objectives Researchers are concerned whether multiple imputation (MI) or complete case analysis should be used when a large proportion of data are missing.

Imputation-based Time-Series Anomaly Detection with Conditional Weight-Incremental Diffusion Models
Knowledge Discovery and Data Mining, 2023Existing anomaly detection models for time series are primarily trained with normal-point-dominant data and would become ineffective when anomalous points intensively occur in certain episodes.

AbstractMissing data are a common problem in statistics. Imputation, or filling in the missing values, is an intuitive and flexible way to address the resulting incomplete data sets. We focus on multiple imputation, which, when implemented correctly, can be a statistically valid strategy for handling missing data.

Abstract This chapter underscores the importance of being able to the norms of practical philosophy in concrete circumstances, particularly as relevant to Kant’s moral theory as expounded in the Groundwork and second Critique. Notably absent in these works is a comprehensive theory or even reflection on the application of moral laws ...

Scandinavian Journal of Statistics, 1998
The method of likelihood imputation is devised under the framework of latent structure models where the observation is a statistic of the complete data which can only be specified on a latent basis. The imputed data set is chosen to differ least from the observed one in their information contents—a concept with general implications for the analysis of ...
