From: Statistical significance approximation for local similarity analysis of dependent time series data
The standardized abundance of Leptotrichia and Kingella (a) from the tongue of ‘F4’ in the MPHM dataset. The autocorrelograms (b, c) of these bacterias show significant autocorrelation. The dashed line represents the critical value of the statistics \(\pm \thinspace 1.96/\sqrt {n}\), where n is the number of time points of the time series. The region bounded by the dashed lines give the pointwise acceptance area for testing the null hypothesis that the autocorrelation functions of time series are zero at the 5% significance level
