Frequency-domain test for fractional cointegration (Souza, Reise, Franco, Bondon (2018))
Frequency-domain test for fractional cointegration (Souza, Reise, Franco, Bondon (2018))
FCI_CH06 Semiparametric frequency-domain test for fractional cointegration by Souza, Reise, Franco, Bondon (2018). Returns test statistic, critical value, testing decision and estimate of the cointegrating strength. Null hypothesis: no fractional cointegration.
FCI_SRFB18(X, d, m, r, alpha =0.05)
Arguments
X: bivariate data matrix.
d: known common memory parameter. However, simulations indicate that consistent memory estimation does not invalidate the test.
m: bandwith parameter specifying the number of Fourier frequencies used for the estimation, usually floor(1+T^delta), where 0<delta<1.
r: integer trimming parameter, r>0.
alpha: desired significance level. Default is alpha=0.05.
