vcovx

vcovx.default

vcovx.negbin

An extension to the <code><a href="/link/vcov?package=MASSExtra&version=1.2.2" data-mini-rdoc="MASSExtra::vcov">vcov</a></code> function mainly to
cover the additional parameter involved in negative binomial models.
(Currently the same as <code><a href="/link/vcov?package=MASSExtra&version=1.2.2" data-mini-rdoc="MASSExtra::vcov">vcov</a></code> apart from negative binomial models.)

Some enhancements, extensions and additions
to the facilities of the recommended 'MASS' package
that are useful mainly for teaching purposes, with
more convenient default settings and user interfaces.
Key functions from 'MASS' are imported and re-exported
to avoid masking conflicts.  In addition we provide
some additional functions mainly used to illustrate
coding paradigms and techniques, such as Gramm-Schmidt
orthogonalisation and generalised eigenvalue problems.
