An object of class p2canon that contains information derived from two
formulae using projs.2canon.
A list of class p2canon. It has two components: decomp and
aliasing. The decomp component iscomposed as follows:
It has a component for each component of Q1.
Each of the components for Q1 is a list;
each of these lists has one component for each of
Q2 and a component Pres.
Each of the Q2 components is a list of three
components: pairwise, adjusted and Qproj.
These components are based on an eigenalysis of the
relationship between the projectors for the parent Q1
and Q2 components.
Each pairwise component is based on the nonzero
canonical efficiency factors for the joint decomposition of
the two parent projectors (see proj2.eigen).
An adjusted component is based on the nonzero
canonical efficiency factors for the joint decomposition of
the Q1 component and the Q2 component,
the latter adjusted for all Q2 projectors that have
occured previously in the list.
The Qproj component is the adjusted projector for the
parent Q2 component.
The pairwise and adjusted components have the
following components: efficiencies, aefficiency,
mefficiency, sefficiency, eefficiency,
xefficiency, order and dforthog
-- for details see efficiency.criteria.
The aliasing component is a data.frame decribing the aliasing between
terms corresponding to two Q2 projectors when estimated in subspaces
corresponding to a Q1 projector.
