autocorrelation

A measure of how closely a signal in a time series resembles a time-delayed image of itself—periodic signals are highly autocorrelated; random signals are not.

Now the kernel's autocorrelation is highly evident and De-autocorrelation can begin.
Firstly, the vibration signal is processed by the autocorrelation based multi-structure elements difference morphological filter.
The Lag 2 autocorrelation equal to 0.24 is obtained by calculating the correlation of columns B and D (between [y.sub.t] and [y.sub.t-2]), and so forth.
Local indicators of spatial autocorrelation identified 19 statistically significant districts, while no evidence of clustering was found at the global/country level.
1) Autocorrelation test: Instead of using the Gaussianity, the autocorrelation tests the whiteness of the separated signals.
We analyzed and discussed these data thoroughly and the plot of autocorrelation functions.

Spatial Autocorrelation. To examine spatial patterns, this research makes use of the Moran's I Index to measure spatial autocorrelation.
The level of autocorrelation in the data (high [rho] values, which lower the effective n) tends to increase as the time interval becomes smaller.
Finally, we conducted a generalized linear mixed model (GLMM) grouping nearby sampling sites (< 60 m apart), in three groups (low, middle and high elevation), following recommendations provided by the autocorrelation analysis.
The description includes methods based on calculating the correlation coefficient between autocorrelation of a binary sequence received and a pattern sequence as well as methods used for filtering the presence of binary patterns.
