Get harmonics for the seasons
stsm_harmonics(freq, decomp = "", seasons = NULL, wavelet = FALSE)
Frequency of the data
Decomposition model ("tend-cycle-seasonal", "trend-seasonal", "trend-cycle", "trend-noise")
The seasonal periods: i.e. c(365.25, 7 if yearly and weekly seasonality). Default is NULL and will be estimated via wavelet analysis.
Whether seasons were detected using wavelet analysis
