I have run the common Pathways multivariate model for my data. When I total up the specific genetic variance and genetic variance from the latent variable to each of the phenotypes, I am getting less than 100%. I am also getting less than what the model says is the total genetic variance (from stA in the model attached). Is there anything I am doing wrong?
(output for one of my variables:
stA 0.3060186 (overall heritability)
specific heritability (stas^2) 0.07233587
specific environment (stes^2) 0.3732820
latent heritability contribution (h2c) 0.1749177
Latent unique environment (e2c) 0.2400518)
Also I am getting different total heritability values (again from stA in the model) than what I am getting when I run each of the variables through a univariate model. Would this be correct or does it indicate a problem?
