Final, generalised mixed-effect model for genotype modelled against left hemisphere volumes.

<p>Formula: Genotype ∼ Left Hippocampus + (1|Age).</p><p>Fixed effects:</p><p>A generalised mixed-effect model is run using normalised volumes of left hemisphere grey matter structures and gender as explanatory variables together with age as a random effect. Genotype is set as the response variable. The final model is derived following an iterative model selection procedure that involves comparing successive models using Akaike's Information Criterion (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0048895#s2" target="_blank">Methods</a> for detailed description of model selection procedure).
