FCI_WWC15: Semiparametric test for fractional cointegration (Wang, Wang,...

In LongMemoryTS: Long Memory Time Series

Description

FCI_WWC15 Semiparametric implementation of the testing strategy for fractional cointegration by Wang, Wang, Chan (2015). Returns test statistic, critical value and testing decision. Null hypothesis: no fractional cointegration.

Usage

FCI_WWC15(X, m, mean_correct = c("init", "mean", "weighted", "none"),
  alpha = 0.05)

Arguments

X	bivariate data matrix.
m	bandwith parameter specifying the number of Fourier frequencies used for the estimation, usually floor(1+T^delta), where 0<delta<1.
mean_correct	specifies the form of mean correction in the memory estimation.
alpha	desired significance level. Default is alpha=0.05.
