Hi Mohamed!

Thanks for reaching out!

The DataFrame contains a large number of unique models (312) in the Model column, which presents a challenge for regression analysis due to the high dimensionality associated with creating dummy variables for each unique model. However, much of the information captured in the "Model" column can be derived from the Brand, Year, and EngineV columns. Therefore, dropping the Model column would simplify the regression construction process.

Hope this helps.
