periodogram is the Fourier transform of the autocovariance function. An equi-spaced time series is one in which the distance between adjacent points is constant. The periodogram (or spectrum) for a time series xt is: (EQ 2-18) R is the amplitude,

The periodogram (a scaled squared FFT) shows strong concentrations of variance in frequencies close to zero --exactly which cannot be ascertained from your plots. The periodogram is an inconsistent estimator of the spectrum of a stationary time series, hence the very erratic behaviour you see in your second plot.

As expected ( link1, link2 ), the periodogram displays a a highly significant maximum peak at a frequency of ~11 years. The function comes from a nice set of functions that I found here: http://research.stowers-institute.org/efg/2005/LombScargle/R/index.htm.

The periodogram is very easy to implement in R, but before we do we need to simulate some data. The code below first uses the set.seed command so R will produce the same “random” numbers each time.

Then, we 3.4 Spectral Analysis. The above derivation of Parseval’s theorem suggest that there may be some value to examining the values of \(R_p^2/2\) as a function of \(p\).Roughly speaking (modulo a few constants of proportionality), a plot of \(R_p^2/2\) vs. \(p\) is called the raw periodogram and is a plot of the energy in each frequency range as a function of the frequency. the periodogram, its statistical properties, and significance tests are described.

The periodogram is very easy to implement in R, but before we do we need to simulate some data. The code below first uses the set.seed command so R will produce the same "random" numbers each time. Then it creates a 32 normally distributed numbers and 32 points of a sine wave with a normalized frequency of 0.4 and a amplitude of 2.

This occurs when all the vectors line up and point in the same direction, creating high values that represent the “power” of the frequency. Thanks for contributing an answer to Stack Overflow!
