Coef.rrvglm-class {VGAM} | R Documentation |
The most pertinent matrices and other quantities pertaining to a RR-VGLM.
Objects can be created by calls of the form
Coef(object, ...)
where object
is an object
of class rrvglm
(see rrvglm-class
).
In this document, M is the number of linear predictors and n is the number of observations.

:colx1.index
:"vlm"
-type model matrix corresponding to the variables
in x1. These correspond to B1.
colx2.index
:"vlm"
-type model matrix corresponding to the variables
in x2. These correspond to the reduced-rank regression.
Atilde
:"matrix"
, the
A matrix with the corner rows removed. Thus each of the
elements have been estimated. This matrix is returned only
if corner constraints were used.
