PerQn {tsqn}

Robust periodogram based on the Robust ACF

Description

Computes the robust pseudo-periodogram of Molinares et al (2009) based on the robust ACF by Ma and Genton (2000).

Usage

PerQn(x, window = "truncated", bandw.rob = 0.7)

Arguments

x

univariate time series

window

character string giving the type of the window. Allowed values are "truncated" (the default) or "NULL".

bandw.rob

is a numeric value giving the truncation point.

Value

a numeric vector containing the values of the robust periodogram proposed by Molinares (2009).
