create a column plot of the autocorrelations of data
data set (1-dimensional), DataSeries
(optional) equation(s) of the form option=value where option is one of lags or nocaption or any option recognized by Statistics[ColumnPlot].
The Correlogram command computes autocorrelations of the data X and displays them as a column plot with dashed lines indicating the lower and upper 95% confidence bands for the normal distribution N⁡0,1L, where L is the size of the sample X, and a caption reporting how many of the displayed columns lie outside of the bands of plus or minus 2, 3, and 4 standard deviations respectively.
The AutoCorrelationPlot command is provided as an alias.
Autocorrelation can be used to create correlograms which are useful for detecting periodicity in signals.
Periodicity in a time series can be observed with Autocorrelation.
