# Extension: correlated RE's

Correlated RE's

Add random effects to all 3 phi's, and attempt to estimate correlations

The purpose of this example is to show one way of implementing correlated random effects.
The example is supposed to be a template for building models with correlated random effects, AND THE
PROVIDED DATASET IS NOT MEANT TO GIVE ANY MEANINGFUL RESULTS.
As a starting point we take the logistic growth-curve model studied the
orange data example. In that model there
are three parameters (f

_{2}, f_{2}, f_{3}), of which only f_{1}is associated with a random effect. Here, we extend the model by including a random effect for all three parameters, and the random effects are allowed to be correlated as explained in the ADMB-RE.
