Repeated measures


Working with asreml using polynomial random regressions I have the same
problem than Dave Johnson: 0 covariance between the polynomial
coefficients. If I specify a US matrix with 0 covariances or a DIAG
matrix the program works, but trying to specify covariances different
from 0 leads to non-convergence.  Does anyone know why this happen?

Another related question: If I use just a DIAG structure and then check
the .sln file there is a problem with the identities of the solutions.
Each identity looks like a series of black squares followed by .001,
.002, etc. So, I know what solution corresponds to each term of the
polynomial, but I can't know to what individual.

If it is of any help, I'm using asreml version April 16 1998 for win95.

Thanks a lot,
