Find Aliases (Dependencies) in a Model

Brown Brown Nunn Bush Schooner Oxford Men's Description

Find aliases (linearly dependent terms) in a linear model specified by a formula.

Nunn Brown Men's Bush Brown Oxford Schooner Usage

alias(object, ...)

## S3 method for class 'formula'
alias(object, data, ...)

## S3 method for class 'lm'
alias(object, complete = TRUE, partial = FALSE,
      partial.pattern = FALSE, ...)

Arguments

Polen Women's As25 Charcoal Slipper Classic Haflinger w4pxTgqwStanley Soft Men's Toe 2 Industrial 0 Shoe and Construction Black Dropper 4I4wZxr
object

A fitted model object, for example from lmBoot Surge Espresso Chukka Toe Waterproof Plain Men's Nubuck Waterproof Storm Rockport wx7qE048T or aov, or a formula for alias.formula.

data

Optionally, a data frame to search for the objects in the formula.

complete

Should information on complete aliasing be included?

partial

Should information on partial aliasing be included?

partial.pattern

Brown Men's Nunn Brown Oxford Bush Schooner Should partial aliasing be presented in a schematic way? If this is done, the results are presented in a more compact way, usually giving the deciles of the coefficients.

Although the main method is for class "lm", aliasLucky Heeled Women's Sandal Xaylah Brand Laguna rqt05rw is most useful for experimental designs and so is used with fits from aov. Complete aliasing refers to effects in linear models that cannot be estimated independently of the terms which occur earlier in the model and so have their coefficients omitted from the fit. Partial aliasing refers to effects that can be estimated less precisely because of correlations induced by the design.

Some parts of the "lm" method require recommended package Running Max Black Shoes wolf Mens Essential NIKE Grey Air White Zero qSaxPA to be installed.

Oxford Nunn Brown Men's Bush Brown Schooner Note

The aliasing pattern may depend on the contrasts in use: Helmert contrasts are probably most useful.

The defaults are different from those in S.

Author(s)

The design was inspired by the S function of the same name described in Chambers et al (1992).
