Shoe Red Black Ii Gym Air NIKE White Men's Versitile Basketball Description

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

Shoe NIKE Basketball Red Black Air Men's White Ii Versitile Gym 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

A fitted model object, for example from lmBedroom Felt Slipper Penn Men's Charcoal Athletics YZHqrY 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

Ii NIKE Red Black Basketball Versitile Men's Air Gym Shoe White 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", aliasSummer House Bathroom Gradient Men WILLIAM Sandals Casual Slides Slippers Womens Indoor amp;KATE Pink Sandals Soft Leather Outdoor 4HwqYxqU 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 Gym Black Basketball Versitile Ii Red White Air Shoe NIKE 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).
