11 Functions of variance components 174A more detailed exampleFor convenience in preparing the .pin file, some users copy the variance componentlines from the .asr file and insert them at the top of the .pin file, beingcareful to retain one leading space so that the lines will be just copied and otherwiseignored as the .pin file is processed.The following sample .pin file is a little morecomplicated. It relates to the bivariate siremodel in bsiremod.as shown in the code boxto the right.The first six lines of the .pin file contain thevariance component table on which the .pinfile is based, copied from the the .asr file forconverience in coding the rest of the file.Bivariate sire modelsire !Iywt fatbsiremod.asdywt fat ∼ Trait !r Trait.sire1 2 10 # ASReml will count unitsTrait 0 US3*0Trait.sire 2Trait 0 US3*0sireResidual UnStruct 1 26.2197 26.2197 18.01 0 UResidual UnStruct 1 2.85090 2.85090 9.55 0 UResidual UnStruct 2 1.71556 1.71556 18.00 0 UTr.sire UnStruct 1 16.5262 16.5262 2.69 0 UTr.sire UnStruct 1 1.14422 1.14422 1.94 0 UTr.sire UnStruct 2 0.132847 0.132847 1.88 0 UF phenvar 1:3 + 4:6F addvar 4:6 * 4H heritA 10 7H heritB 12 9R phencorr 7 8 9R gencor 4:6Numbering the parameters reported in bsiremod.asr (andbsiremod.vvp)123456thenerror variance for ywterror covariance for ywt and faterror variance for fatsire variance component for ywtsire covariance for ywt and fatsire variance for fat
