Periodic autocovariances to use for illustration of maximum entropy completion.
data(pcme.someex)
A list of five 5 x 2 matrices, each (possibly) representing periodic autocovariances of a periodically correlated time series with period T=2. The "possibly" qualifier is used because it may not be possible to complete these to complete periodic autocovariance sequences.
The ordering is the season-lag ordering used for all function in
package pcme
. Let
R_k(l)=Cov(X(k),X(k-l)) for k=1,2
and l=0,1,2,3,4. Then the arrangement of the autocorrelations in
each matrix is as follows:
R_1(0) | R_1(1) | R_1(2) | R_1(3) | R_1(4) |
R_2(0) | R_2(1) | R_2(2) | R_2(3) | R_2(4) |
