## Description of a p2canon object

### Description

An object of class `p2canon`

that contains information derived from two
`formulae`

using `projs.2canon`

.

### Value

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.
