Dear members,
I could not get asreml1.10 to constrain the fixed effect of contemporary
group (HYS) successfully in my analyses (by fitting c(HYS) in the model).
Asreml still always puts mean of one of the HYS levels to zero.
Would this be because I have too many levels of HYS? if so, up to how many
levels of an effect can we constrain (sum to zero)?
By the way, for effects that do not have many levels, the constraint
command was working fine in my analyses using asreml1.10.
Many thanks
