Re: Repeated observations



Dear Abbas,

Your ASREML job is not correct enough for me to know what you want to do.

If you want to fit a simple repeatability  model  the job should be

Data of Rado to estimate heritability
 IND  !I
 SIRE !M-99
 SEX  !M-99
 HBOOK 4 !I
 AGE
 BW
 DG
rado2.prn   !MVINCLUDE
 DG ~ mu SEX HBOOK !r IND 

I do not understand why you have missing SEX information.
Typically  Sex would appear as
  SEX !A     # if coded alphabettically Male Female
  SEX !L Male Female  # if coded 1 (for Males), 2 for Females.

If you wanted to estimate genetic variance and nongenetic variance,
the model might be
