Regarding Normalization in Time Series.

Hey Ganesh,   We wanted to introduce normalization because it's the correct approach when we're comparing multiple time-series together. My personal experience with contagion analysis has shown that normalizing the data removes limitations of the approach, since the different variables in the analysis can vastly vary in magnitude.    Here we're just showcasing it because it's a good approach, but you don't have to do it when analyzing a single dataset.    Best, 365 Vik
