Hello,
In question 3 I got different coefficients than the ones in the correct answers:
The differences are really large to be a numerical problem. Are you sure you scaled your data inside a pipeline and did you replace the negative acceleration values by 0 using data["acceleration"].clip(lower=0)?
Thank you for the reply Arturo,
In fact, I didn’t not replace the negative values with 0, I just filtered them out so I guess that’s why I got different results.
