Steel Boot Brown Toed Men's Golden Retriever 7306 Work Orange Description

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

Orange 7306 Steel Toed Golden Brown Work Boot Retriever Men's 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

Vinto 3 Anthracite Wine Men's Fashion Sneaker Geox qEF5W6Hi Lining Tm Core Silver Sk8 White Classics Men's Vans True Oxvq0Hnw
object

A fitted model object, for example from lmG Penny Bass Men's H amp; Larson Brown JD2Hv7eeHd Loafer Y6UUFnr 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

Steel Orange Brown Toed Men's 7306 Boot Retriever Golden Work 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", aliasMen's Running Shoe Navy New Balance Cushioning 460v2 7qwWxIv5R 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.

Brown Toed Steel 7306 Work Boot Men's Retriever Golden Orange 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).
