The AIREMLF90-type heterogeneous residual variance version of BLUP90IOD2.
See BLUP90IOD2 for other options.
See PREGSF90 with genotypes (SNP) for options.

Heterogeneous residual variances for a single trait

OPTION hetres_pos 10 11

Specify the position of covariables.

OPTION hetres_pol 4.0 0.1 0.1

These values are on the natural log scale.

Heterogeneous residual variances for multiple traits

OPTION hetres_pos 10 10 11 11

or

OPTION hetres_pos 10 11 12 13

Specify the position of covariables (trait first). “10 10” or “10 11” could be linear for first and second traits.
“11 11” or “12 13” could be quadratic.

OPTION hetres_pol 4.0 4.0 0.1 0.1 0.01 0.01
