Table 3 t values of Hotelling Williams t test in difference between correlations (correlation between genomic prediction and true breeding value) from the single- trait and the multiple-trait models

From: Comparison of single-trait and multiple-trait genomic prediction models

Trait Data type Hotelling Williams t value
GEBV_m GEBV_s
I No missing for both traits 0.000 0.000
Missing for trait I 7.156** 6.237**
II No missing for both traits 0.718 2.701
  Missing for trait II 8.079** 8.883**
  1. **Significantly different (P > 0.01).
  2. GEBV_m: the genomic estimated breeding value (GEBV) predicted using the EBV response variable estimated from the conventional multi-trait linear mixed model.
  3. GEBV_s: the GEBV predicted using the EBV response variable estimated from the conventional single-trait linear mixed model.
