[R-sig-ME] Animal model residual value

[Walid]

Hi everyone,

I have a question on a certain assumption made regarding the 'animal' 
model when implemented in a quantitative genetic study for a trait. 
While reading van Benthem et al. (2016), the author mentions that the 
residual (environmental) value, in the additive partitioning assumed by 
the model, captures plasticity. Does this assumption always hold? or 
only in the case where we model the maternal, permanent environment and 
common environment?

My question is for the purpose of estimating the plasticity of a fixed 
heritable life-history trait (occurs only once during individual 
lifetime). Since there are no explicit methods to estimate individual 
plasticity in a non-labile trait, I am attempting to see if I can 
circumvent this by using the 'animal' model based on the assumption 
mentioned above.

Thank you
