  With some difficulty, yes.  I seem to have posted partial answers
to this on Rpubs twice:


The latter is later, but it might be worth looking at both of them
(at some point I should reconcile them ...)

Keep in mind that the asymptotic variances of the variance estimates
are often very inaccurate summaries of the uncertainty ...
