can_lm: Transform a Multivariate Linear model mlm to a Canonical Representation

Description

This function uses candisc to transform the responses in a multivariate linear model to scores on canonical variables for a given term and then uses those scores as responses in a linear (lm) or multivariate linear model (mlm).

The function constructs a model formula of the form Can ~ terms where Can is the canonical score(s) and terms are the terms in the original mlm, then runs lm() with that formula.

Usage

can_lm(mod, term, ...)

Value

A lm object if term is a rank 1 hypothesis, otherwise a mlm object

Arguments

mod

A mlm object

term

One term in that model

...

Arguments passed to candisc
