I have had difficults to set up a bivariate
animal model with one (0, 1) trait (two years-old pregnancy rate) and one
normally distributed trait (yearling weight).
- the records of pregnancy rate (females after
selection) were obtained for 1/3 of the total animals wich have records of
yearling weight (males and females before selection). Can it cause any
problem in this kind of bivariate analysis?
-because of the missing data, I put "9" in the data
file to indicate missing values for pregnancy rate, and put !m9 in .as
file. Can I make this?
-after run, with sucess, the univariate analysis
for weight and p.rate with the data file with "9" in the missing values, I make
the following .as file to run an bivariate analysis:
