Description

R code demonstrating the use of the peacots package for the periodogram analysis of a few example time series using the WN and OUSS null models. Includes all necessary data. The files cyclic and non_cyclic contain simulated time series of a cyclic and non-cyclic OUSS processes, respectively. The files GPDD_407 and GPDD_9711 contain the two GPDD time series used as examples in the main article. To execute the code, run source(“example.R”) in R. More details are given in the Readme.rtf file. More examples are available as part of the peacots documentation.
