%description
Spectral and Average Autocorrelation Zero Distance Density ('sazed') is a
method for estimating the season length of a seasonal time series. 'sazed'
is aimed at practitioners, as it employs only domain-agnostic
preprocessing and does not depend on parameter tuning or empirical
constants. The computation of 'sazed' relies on the efficient
autocorrelation computation methods suggested by Thibauld Nion (2012, URL:
<https://etudes.tibonihoo.net/literate_musing/autocorrelations.html>) and
by Bob Carpenter (2012, URL:
<https://lingpipe-blog.com/2012/06/08/autocorrelation-fft-kiss-eigen/>).
