Summary

Fit imputer on selected columns and transform data

Inputs

• columns (required) — Comma-separated list of columns to impute
• strategy — Imputation strategy (mean, median, most_frequent, constant)
• fillValue — Value to use for constant strategy
• pythonPath — Path to Python executable with scikit-learn installed

Output shape

A list of records; each record includes the original data with the selected columns replaced by their imputed values
