FCI_CH06 {LongMemoryTS}

Residual-based test for fractional cointegration (Chen, Hurvich (2006))

Description

FCI_CH06 Semiparametric residual-based test for fractional cointegration by Chen, Hurvich (2003). Returns test statistic, critical value and testing decision. Null hypothesis: no fractional cointegration.

Usage

FCI_CH06(X, m_peri, m, alpha = 0.05, diff_param = 1)

Arguments

X

data matrix.

m_peri

fixed positive integer for averaging the periodogram, where m_peri>(nbr of series + 3)

m

bandwith parameter specifying the number of Fourier frequencies used for the estimation, usually floor(1+T^delta), where 0<delta<1.

alpha

desired significance level. Default is alpha=0.05.

diff_param

integer specifying the order of differentiation in order to ensure stationarity of data, where diff_param-1 are the number of differences. Default is diff_param=1 for no differences.
