Estimate of mu

Dear All:

I need to estimate the population mean (mu). I understand that mu can
be estimated from the following model if there is no singularity.

Y ~ mu c(site) c(group) c(site).c(group) !r site.group.rep tree site.family

If singularity exists, however, can I use the following PREDICT
statement to get the correct estimate of mu?

Y ~ mu site group site.group !r site.group.rep tree site.family
predict mu !present site group !average tree

Thanks a lot!
