Can someone help me to understand what is going wrong with the following code?
The code is to estimate the covariance parameters employing mixed model analysis with the classical animal model used in breeding. There are 3 fixed effects F1=2 levels, F2=11 levels and F3=2 levels. Individual animals (1413 Nos) are considered as random effects. am is the additive genetic relationship matrix or numerator relationship matrix. The same procedure from proc mixed using REML is tried to implement through the following code. The output from MIVQUE0 module is the starting value for the minimization of -2loglikelihood. I cannot understand why the following error happens.
