Guided Notes

3 key concepts

  • 1

    When data appears non-linear, we can still apply linear regression tools by transforming the data.

  • 2

    In the video's example, plotting x versus log(y) reveals a linear pattern that can be analyzed using linear regression.

  • 3

    Transforming data allows us to use existing linear regression tools, and we can mathematically convert the model back to the original relationship.
