Simple Periodogram Estimate
Description
Simply estimate the periodogram via the Fast Fourier Transform.
Usage
per(z)
Arguments
z
numeric vector with the series to compute the periodogram
from.
Details
This is basically the same as
spec.pgram(z, fast = FALSE, detrend = FALSE, taper = 0) $ spec,
and not really recommended to use — exactly for the reason that
spec.pgram has the defaults differently,
fast = TRUE, detrend = TRUE, taper = 0.1, see that help page.
Value
numeric vector of length 1 + floor(n/2) where n = length(z).
Author(s)
Jan Beran (principal) and Martin Maechler (fine tuning)
See Also
a more versatile periodogram estimate by
spec.pgram.
Examples
data(NileMin)
plot(10*log10(per(NileMin)), type='l')
