Summary
In this chapter, we learned a number of sophisticated signal processing techniques. Most of them were applied to a dataset of sunspot data. We looked at smoothing with window functions and moving averages. We also touched upon the sifting process used by scientists to derive sunspot cycles. Last but not least, a demonstration was given of cointegration.
In the next chapter, we will focus on debugging, profiling, and testing, including assert functions and various tools.
