azed function

Compute the AZED component of the SAZED ensemble

azed computes the autocorrelation of its argument, and then derives the season length from its the autocorrelations zero density.

azed(y, preprocess = T)

Arguments

• y: The input time series.
• preprocess: If true, y is detrended and z-normalized before computation.

Returns

The AZED season length estimate of y.

Examples

season_length <- 26
y <- sin(1:400*2*pi/season_length)
azed(y)
azed(y, preprocess = FALSE)
