Thanks, Dmitri,
Yes, I’ve given a Simple Linear Regression example to a couple of Data Analysts, and they seem to skip the autocorrelation test, in fact, they seem to depend on X and Y correlation R-Squared, and charts only.
A professor told me that I should find out why there is autocorrelation in the residuals. This makes sense but I am not really sure how to go about it given a domain I am not really familiar with.
