7.5 Animal model Breeding value estimation

  preseding page

Animal model breeding value estimation uses all the information from all the measured animals, therefore it is one advantage if you can set up the inverse relationship matrix directly without having to invert it, when it comes to large populations, see the following link .

As you can see, the inverse relationship matrix has a very simple structure, link to the theory of the simple structure.
