Next step is to “bin” the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval. Here we have defined bins = 10. So, there are a total of 100/10 = 10 intervals. 6. Scatter plot. import matplotlib.pyplot as plt # x-axis values . x = [1,2,3,4,5,6,7,8,9,10]

If two series show a specific trend towards a mean-reverting equilibrium over time, the quality of this mean reversion can be tested for stationarity and stability. Correlations may only occur over a short time period, whereas co-integration models should revert over time to a stationary mean-reverting value – a linear equilibrium level.
