My dataset contains some stocks and some bitcoin titles. I would like to replace NA data (normal stocks are not traded on sat. and sun.) using a regression on the stock itself. How can i do this?

Set the column with missing values as your target.

Remove rows where your target is null.

Train a regression model that predicts your target using the rest of your features.

Replace missing values with this regression model's predictions.
