Dear members of the ASREML discussion group:
Similar to Hugo Montaldo I am analyising binomial trait (0 and 1's) and I
believe it has a direct and maternal (genetic and permanent) effects. I
obtained the following results with the !logit option:
Variance heterogenity factor [Deviance/DF] 0.68
Source Model terms Gamma Component Compnt/StndErr
ide(dam) 22236 5278 0.289821 0.289821 3.35 U
anim US=UnStr 1 0.937505E-01 0.937505E-01 2.32 U
anim US=UnStr 1 -0.251243E-01 -0.251243E-01 -0.51 U
anim US=UnStr 2 0.129291 0.129291 1.60 U
Covariance/Variance/Correlation Matrix US=UnStructu
0.9375E-01-0.2282
-0.2512E-01 0.1293
I understand that ide(dam)=0.289821 is the variance of maternal permanent
effect, anim=0.937505E-01 is the variance of direct effect,
anim=-0.251243E-01 is the covariance between direct and maternal genetic
effect and anim=0.129291 is the variance of maternal genetic effect.
How can I estimate heritabilities for direct and maternal genetic effects
and their s.e.'s in both the original and underlying scale?.
Thanks
Nicolas
