FCI_NS07: Rank estimation in fractionally cointegrated systems by...

In LongMemoryTS: Long Memory Time Series

Description

FCI_NS07 Rank estimation in fractionally cointegrated systems by Nielsen, Shimotsu (2007). Returns estimated cointegrating rank, r=0,...,dim-1.

Usage

FCI_NS07(X, m, m1, mean_correct = c("mean", "init", "weighted", "none"),
  v_n = m^(-0.3))

Arguments

X	data matrix.
m	bandwith parameter specifying the number of Fourier frequencies used for the estimation of G, usually floor(1+T^delta), where 0<delta<1 and m1>m.
m1	bandwith parameter specifying the number of Fourier frequencies used for the memory estimation , usually floor(1+T^delta1), where 0<delta1<1 and m1>m.
mean_correct	specifies the form of mean correction in the memory estimation.
v_n	bandwidth parameter. Nielsen and Shimotsu (2007) use m^(-0.3) in their simulation studies, which is the default value. m^(-b) mit 0<b<0.5 can be used.
