Although the main method is for class "lm", aliasRN Women's Black Pink deadly Dark Raisin Running Free Flyknit 2017 Shoe NIKE UEq7SwFq 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.

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).
