FCI_ZRY18: Rank estimation in fractionally cointegrated systems (Zhang, Robinson, Yao (2018))

Description

FCI_CH06 SRank estimation in fractionally cointegrated systems (Zhang, Robinson, Yao (2018)). Returns estimated cointegrating rank, r=0,...,dim-1.

Usage

FCI_ZRY18(X, lag_max, lag_max2 = 20, c0 = 0.3)

Arguments

X

data matrix.

lag_max

number of lags in autocovariance matrix of data for eigenvector estimation.

lag_max2

number of residual autocorrelations that are averaged, default is m=20 as recommended by Zhang, Robinson, Yao (2018).

c0

threshold to compare averaged residual autocorrelation to, default is c0=0.3 as recommended by Zhang, Robinson, Yao (2018).
