ToeplitzBlock | R Documentation |
Block Toeplitz matrix of order m+1
with k\times k
auto-cross correlation matrices.
The Hosking (1980) definition of the correlation matrix is used.
This is needed for the function MahdiMcLeod
.
ToeplitzBlock(res,Maxlag)
res |
residuals, numeric or matrix. |
Maxlag |
an integer number = |
A block Toeplitz matrix of auto and cross correlation matrices using Hosking (1980) definition
from lag
= 0
to lag
= m
.
