1. When does a linear regression model exist?

When the four assumptions hold.

It always exists, its just the line of best fit on data.

When there is stat. sign. Correlation between the indep. And response.

It depends.

Why do we care about the assumptions of assumed linear model?

If they hold then that validates our choice of linear model.

If they hold we can attempt to do inference with the model.

Knowing which assumptions hold can help us understand the performance of our model, even if it’s not perfectly accurate

All of the above

None of the above

What does the assumption of independence refer to?

Independence between response (Y) and covariate (X)

Independence between response (Y) and error term (epsilon)

Independence between covariate (X) and error term (epsilon)

Independence between response (Y), covariate X, and error term (epsilon)
