Witryna2 cze 2024 · To overcome this problem, several researchers used the imputation method as a process of replacing missing data with substituted values. Rubin [ 1] introduced three concepts: MAR (missing at random), OAR (observed at random), and PD (parameter distribution). Witryna29 lip 2024 · We also found that several methods show more compromised performance in missing value imputation such as scGNN and scScope. scGNN utilized the imputation autoencoder and pre-processed matrix to recover gene expression matrix which may lead to an exaggerated deviation between raw data matrix and imputation …
