xrand1: Correlation structural breaks variable 1

Description

Simulated data showing correlation structural breaks in Figure 4 of Fern<U+00E1>ndez-Macho (2018).

Usage

data("xrand")

Format

A data frame with 512 observations on 1 variables.

xrand1

a numeric vector

Details

\(xrand1[t]\) and \(xrand2[t]\) are highly correlated at low frequencies (long timescales) but uncorrelated at high frequencies (short timescales). However, during a period of time spanning the second third of the sample (\(T/3<t<2T/3\)) that behavior is reversed so that data become highly correlated at short timescales but uncorrelated at low frequencies.
