Mechanism-aware imputation: a two-step approach in handling missing values in metabolomics

BMC Bioinformatics

Table 1 Effect of γ parameter on missingness patterns

γ (%)	Effect	Percentage in imposed oracle data
12	More MCAR \| less MNAR	90% MCAR \| 10% MNAR
23	More MCAR \| less MNAR	80% MCAR \| 20% MNAR
47	Moderate MCAR \| moderate MNAR	60% MCAR \| 40% MNAR
59	Less MCAR \| more MNAR	49.5% MCAR \| 50.5% MNAR

Columns indicate the effect on the ratio of MCAR to MNAR and the percentage of different types of missing data (MCAR versus MNAR) based on varying γ
