How do you interpret autocorrelation values?
Testing for Autocorrelation
Values closer to 0 indicate a greater degree of positive correlation, values closer to 4 indicate a greater degree of negative autocorrelation, while values closer to the middle suggest less autocorrelation.
How do you read an autocorrelogram?
The value of autocorrelation ranges from -1 to 1. A value between -1 and 0 represents negative autocorrelation. A value between 0 and 1 represents positive autocorrelation.
What is the autocorrelation sequence?
Autocorrelation is the coefficient of linear correlation between two terms of a sequence of random variables. Autocorrelation is also called serial correlation. Definition. Autocorrelation and weakly stationary sequences.
How do you describe the autocorrelation function?
The autocorrelation function (ACF) defines how data points in a time series are related, on average, to the preceding data points (Box, Jenkins, & Reinsel, 1994). In other words, it measures the self-similarity of the signal over different delay times.
