Once we’ve calculate a rolling correlation between two time series, we can visualization the rolling correlation using a simple line chart. How to Visualize Rolling Correlations in Excel For example, we could instead calculate the rolling 6-month correlation: Note that we could use a longer rolling time frame if we’d like as well. We can then drag this formula down to the rest of the cells in the column:Įach cell in the column titled “Rolling 3-month correlation” tells us the correlation between the two product sales for the previous 3 months. For example, here’s how to calculate the first 3-month rolling correlation between the two time series: To calculate the 3-month rolling correlation between the two time series, we can simply use the CORREL() function in Excel. Suppose we have the following two time series in Excel that display the total number of products sold for two different products during a 20-month period: How to Calculate Rolling Correlations in Excel This tutorial explains how to calculate and visualize rolling correlations in Excel. One benefit of this type of correlation is that you can visualize the correlation between two time series over time. ![]() ![]() Rolling correlations are correlations between two time series on a rolling window. ![]()
