string; method to estimate the entropy from discrete
probabilities pi; here probabilities are the spectral density
evaluated at the Fourier frequencies,
pi=f(ωi).
spectrum.method
string; method for spectrum estimation; see method
argument in mvspectrum.
threshold
numeric; values of spectral density below threshold are set to
0; default threshold = 0.
smoothing
logical; if TRUE the spectrum will be
smoothed with a nonparametric estimate using gam
and an exponential family (with link = log). Only works
for univariate spectrum. The smoothing
parameter is chosen automatically using generalized cross-validation
(see gam for details). Default: FALSE.
base
logarithm base; entropy is measured in “nats” for
base = exp(1); in “bits” if base = 2 (default).
