Compute the ZED component of the SAZED ensemble
zed
computes the zero density of its argument, and then derives the season length from it.
zed(y, preprocess = T)
y
: The input time series.preprocess
: If true, y is detrended and z-normalized before computation.The ZED season length estimate of y.
season_length <- 26 y <- sin(1:400*2*pi/season_length) zed(y) zed(y, preprocess = FALSE)
