period.wge {tswge}

Calculate the periodogram

Description

Given a realization contained in a vector, this function calculates and optionally plots the periodogram in either log or non-log scale

Usage

period.wge(x, dbcalc = "TRUE", plot = "TRUE")

Arguments

x

The vector containing the time series realization

dbcalc

if dbcalc=TRUE (default) then the periodogram is calculated in log scale (in dB). If dbcalc is FALSE then the non-log periodogram is calculated

plot

if plot=TRUE (default) the periodogram is plotted. If plot=FALSE no plot is created

Value

freq

Frequencies at which the periodogram is calculated

pgram

Periodogram values evaluated at the frequencies in freq
