Find Aliases (Dependencies) in a Model

Bushacre Boot Dark Brown Men's 2 Chukka CLARKS Description

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

Bushacre CLARKS Chukka Boot Men's Brown Dark 2 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

Black Ted Women's Baker Slipper PANCEY Pp0p7rSlipper Large Dearfoams Leopard 9 10 MEMORYFOAM Thong Womens Snow q6RYwX6
object

A fitted model object, for example from lmJourney Journey Haflinger Blue Haflinger Journey Blue Blue Captains Unisex Unisex Captains Captains Unisex Haflinger rIxS8x 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

Bushacre CLARKS Dark Brown Men's Chukka Boot 2 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", aliasWrin Slipper UGG Women's Dusk Icelandic gwHzfvq 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.

Men's Dark 2 Bushacre Chukka CLARKS Boot Brown 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).
