Hi,
I'm wondering that in which condition we should choose ACE model, or ADE? Is there any criteria to be referred to? For example, in one trait of my own data, the ACE model indicate the CE model is the best fitted model, while the ADE model indicate the DE model is the best fitted model, is this trait heritable? And in the ADE model, how to calculate the heritability? Only the part of A, or the part of A and D, or only the D?
About the result interpreting, is there any criteria help to decide which model is the best fitted model and if the trait is heritable? I found in some paper just using the minus2LL and AIC to choose the best fitted model and in others just comparing the AE model to the E model in which if the model was significantly worsen, then this trait is heritable. Actually I have not found a clear standard criteria to apply the model selection and result interpreting. Is there any recommended literature about it? Many thanks.
