Python for Data Analysis: Step-By-Step with Projects - Tackling Missing Data (Imputing with Model)

This video tutorial covers the final lesson on handling missing data, focusing on using models for imputation. It introduces the iterative imputer from the Scikit-learn library, which estimates missing values by modeling each column as a function of others. The tutorial provides a practical demonstration in Jupyter Lab, showing how to implement this method for numerical columns. It highlights the importance of setting minimum and maximum bounds for imputed values to ensure they remain within a reasonable range. The lesson concludes by saving the imputed data for future use in learning about outliers.
