Approximate accuracy program for animal models including maternal effect and sire models

ACCF90 is a program to calculate reliability for EBV.

OPTION acc_maxrounds 15

Maximum rounds (default 20). Usually, between 10 and 30 but increase the number when the convergence is too large (e.g., > 1d-04).

OPTION conv_crit 1d-06

Convergence criterion (default 1d-06). usually between 1d-04 and 1d-06 but no < 1d-08.

OPTION cg 1 1 2 2

Specify the effect number for contemporary group for each trait. The default is the first effect (= cg 1 1 1 1).

OPTION hs 4

Specify the effect number for herd by sire interaction.

OPTION anim 5

Specify the effect number for animal (required).

OPTION mat 6

Specify the effect number for maternal (required if a maternal effect is included in the model). In a maternal effect model, the next effect of the maternal effect will be automatically the maternal permanent environmental effect (MPE).

OPTION pe 7

Specify the effect number for permanent environment (required if included).

OPTION type 1.0

Select 1.0 for dairy cattle (PTA) or 0.5 for beef cattle (BIF definition) (default 1.0).

OPTION add_residual 8 9

Calculate accuracies adding variances for 8 and 9 random effects to residual variance.

OPTION model animal

Select animal or sire model (default animal).

OPTION parent_avg yes

Output parent averages (default no).
