Inspecting the regression data
The next dataset contains information about company market value over several years of time. This is one of the most popular kind of time series data used for regression. If you can model the value of a company as it changes over time, you can make predictions about where that company will be in the future. This dataset was also originally provided as part of a public Kaggle competition.
In this exercise, you'll plot the time series for a number of companies to get an understanding of how they are (or aren't) related to one another.
