bc_inv

Find the original value corresponding to a box-cox transform

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.
