I hope you enjoy my latest time series question set (P1.T2.21.2). It was fun to develop these with actual code snippets. GARP's text (Chapter 11) on the Augmented Dickey-Fuller (ADF) might seem dense to readers, but you'll see that in R we can execute the test with a single function call, adf.test(). As a practical exam matter, I recommend asking yourself, What is the null hypothesis in the ADF? Then you can identify the implication of a high/low p-value (that's the most likely exam-type question). In the case of my latest factor theory (Andrew Ang) question set, I'm really happy with how the third question turned out (21.2.3): I think this simple visual test is a much better quiz of the low-risk anomaly that my previous questions on the concept. Have a great week!
