  1. Aim: benchmark the quality of missing data imputation and find if imputing data is necessary for decision-making based on the metabolomics data.
    2. Scheme: https://viewer.diagrams.net/?page-id=_Gg_AfVaFpc6PrHJ8jsU&highlight=0000ff&edit=_blank&layers=1&nav=1&page-id=_Gg_AfVaFpc6PrHJ8jsU#G1z9yDcNV2doGwIQaU7gxAmNQtFy5LXXCc
  2. Types of missing values.
  3. Considered imputation methods.
  4. "Safe imputation" https://github.com/michbur/metabolomics-missing-value-imputation/blob/main/functions/imputing.R#L68
  5. Problems:
    7. How to measure the impact on modeling?
    8. Is there a single measure incorporating the quality of imputation and the speed of the imputation?
