Imputation Techniques Visual Tool

Generate a complete dataset, hide selected values, and compare how common imputation methods fill the gaps. Observed data, missing records, and imputed values are drawn together so the statistical trade-offs are visible.

For learning purposes the tool keeps the original complete values behind the scenes. That allows RMSE, MAE, bias, and R-squared to compare each imputation method against the hidden truth.
