Properties of a Cosine Function A periodogram is used to identify the dominant periods (or frequencies) of a time series. This can be a helpful tool for identifying the dominant cyclical behavior in a series, particularly when the cycles are not related to the commonly encountered monthly or quarterly seasonality. Properties of a Cosine Function Because the periodogram maximizer is asymptotically equivalent to the least squares estimator, it follows that the asymptotic properties should mirror those of the maximum likelihood estimator constructed under Gaussian white noise assumptions, that is, under the assumption that the εt are normal, independent, and identically distributed.

The plot of the periodogram shows a sequence of peaks that stand out from the background noise, with the lowest frequency peak at a frequency of just less than 0.1. Periodogram A periodogram is defined by(13.197)|Xjf=jhΔf|2=T|∑i=0N−1xiwiexp−j2πhΔfiT|2=T|∑k=0N−1xiwiexp−j2πhi/N|2,where the scale factor T fixes the PSD unit, and w(i) is a weighting function, known as temporal window, which satisfies ∑i=0N−1w(i)=N (the symbol w has been already applied to weighting variables in Section 10.4). 2020-01-24 Select an empty cell in your worksheet where you wish to generate your output periodogram table and plot.

Suppose that we have observed data at n distinct time points, and for convenience we assume that n is even.
