KNN Imputation

When to Use

Use this skill when you need to remove genes with more than 50% missing values from a bulk expression matrix and then run group-aware KNN imputation, with the donor pool restricted by one grouping column.

Do not use this skill for:

• single-cell data
• multi-column stratification
• non-tabular inputs
• network-dependent workflows
• interactive analysis sessions
