Verify the regression log(breast cancer) ∼ log(colon cancer) + log(colon cancer) 2 must be filtered twice.

i. Fit a regression model to the data.

ii. Use ar.mle() to develop a filtering matrix A based on the residuals from this model.

iii. Fit a filtered regression to the data.

iv. Use ar.mle() to show these residuals appear far from white noise.
