Autocorrelation - PowerPoint PPT Presentation

Pseudo-Noise (PN) sequences are deterministic yet appear random, with applications in various fields such as communication security, control engineering, and system identification. Generated using shift registers, they exhibit statistical properties akin to noise. Linear and nonlinear feedback shift

Statistical models require independent observations, as dependent observations can lead to low p-values and narrow confidence intervals. Generalized and mixed GAM models are used when there is temporal or spatial autocorrelation between observations. Correlation in time series can be analyzed using
