heritability

["Maria Eugênia Mercadante" <meugenia@imagenet.com.br>]

Dear user's,

 

I 'm evaluating calving rate (binary data) during productive life of beef cows, from a selection experiment (two selection lines and a control). I intend to fit a threshold animal model and I make the follow .as file:

 

Calving rate

 cow 5830 !P #animal and pedigree

 ncow 928 !I  # to classifier the permanent environmental of cow

 reb 3 !I        # 3 selection lines

 gc  252 !I

 prena 2 !I

 civm 4 !I

 p550 !-268.4055

 pem !-392.8669

taxap          # calving rate 0 or 1

ped_nel.dat 

taxapre.dat

taxap !BIN !PROBIT ~ mu gc pem p550 prena reb !r cow ncow

 

How can I do to request the genetic variance and heritability in .as file? Would you give me please an example of threshold animal

model for binary data? In these models I really can fit a permanent environmental of cow?

 

best regards

Maria Eugênia
