Budget: $10 – $30 USD

I need help defining the best linear regression solution that generates a spread graph.

No need to program anything. Just run the script I'm uploading as an attachment to parse the script to help me with the definition.

1. The first one I run linear regression and don't normalize the spread.

2. The second I run linear regression and normalize the spread.

3. The third I run the linear regression of a different firm and normalize it differently from the others.

What is the most correct way to generate the spread graph?
