lsmeans



 Dear asreml users,
I run a mixed model using asreml to estimate heritibilities for antibody
measurements. I am interested in least squares means of some fixed effects
and their interations too. In this model, 2 bloodlines, 3 experiment groups
and their interactions (six levels) are fitted as fixed effects. But it is
interesting that three of six lsmeans and stderr for interations are
exactly the same for all 11 bleedings. obiously there is some thing wrong.
Can some one diagnosis  and explain more about the lsmeans output for me? 
Regards,

Yuandan
