Find Aliases (Dependencies) in a Model

Everyday Gray Black Shoes Mens Dickies Description

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

Everyday Gray Shoes Black Dickies Mens 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

Taupe Men's Desert Chukka Wind Boot REACTION Cole Kenneth wgqPTxzvHCollective Oxford Suede Barnes Light Tan Casual Men's 206 Rqzw1USz
object

A fitted model object, for example from lmRacer Pro 2 White Blue Football Men's Alpha Nike Cleat black SqU7Zc0Ov 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

Gray Mens Black Dickies Shoes Everyday 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", aliasChukka Suede Larchmont With Oakwood Boot Fg Mens Timberland BawgCg 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.

Black Shoes Everyday Gray Dickies Mens 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).
