Explained variance

You saw that rent prices between Houston and Las Vegas are correlated. However, to what extent can the price change in one city explain the price change in another city? By computing R-squared you are able to precisely quantify this.

A NumPy array of rents has been loaded for Las Vegas (lasvegas_rents) and Houston (houston_rents), as well as the dates associated with each measurement. The packages pandas as pd, NumPy as np, Matplotlib as plt, and the stats package from SciPy have all been loaded for you.
