Introduction to Regression: Transformations

[@hr-xd8bf]

Hey, thanks for the comprehensive vid! One question about the log transformation for multiple regression models: my model includes two independent variables, of which only one (intensity) is not normally distributed. Can I just log this iv intensity and leave the other iv as it is or do I have to transform both of them?

You can log transform any variable you just need to make sure your interpretation is in the same unit
