12.4.1 multivar computing requests

select trait I [effects M1...]

One `select trait' statement is required for each trait to be modeled. Up to five traits are allowed for multivar.

The trait number, I, corresponds to the column of real numbers in the pedigree file, with the first column of real numbers being trait 1, the second column trait 2 and so on.

M's are the fixed effects to be modeled for a specified trait I. They are the columns in which they appear in the pedigree file, with fixed effect 1 in the 4th column (usually gender), effect 2 in column 5, and so on.
