The regression of ln|res| against Y_hat [to use other notation]
is looking for mean/variance relations.  
A slope of B suggests that Y^{1-B} might have less mean variance relationship.
If there is no mean variance
relation, a slope of zero is expected.  A slope of 1/2 suggest a SQRT 
transformation might resolve the dependence, a slope of 1 means log 
transformation might be appropriate.
So for the 3 traits, log,  Y^{-1) and Y^{-3}

These are standardixed residuals i.e.  residual/{standard deviation}
The standard deviation used is derved from the residuals rather than
me trying to find an appropriate value from the model.
