And you want to calculate the autocorrelation of the data set. Suppose we have data set containing the total number of sales during 10 different time periods. Let’s take a sample scenario wherein we need to calculate autocorrelation in Excel. In this guide, we will discuss two methods to calculate autocorrelation using a combination of the different built-in functions in Excel. But, we can utilize the different built-in functions in Excel to create a single formula that would calculate the autocorrelation. However, there is no single function in Excel to automatically calculates autocorrelation. Additionally, we can use autocorrelation to easily predict future values by referring to the past values of the data set. So autocorrelation is a type of correlation that is used to measure the degree of similarity between a time series and a lagged version of the time series over successive time intervals.įurthermore, autocorrelation is also called serial correlation or lagged correlation because it measures the relationship between the current values of a variable and the past values. For instance, we want to easily calculate a data set’s autocorrelation. Since it has several built-in functions and tools, we can easily perform complex and long calculations. How to Calculate Autocorrelation in ExcelĮxcel is an excellent tool to use for different situations.
