title: 'asremlPlus: Augments ''ASReml-R'' in Fitting Mixed Models and Packages Generally
in Exploring Prediction Differences'
version: 4.4.40
doi: 10.32614/CRAN.package.asremlPlus
abstract: 'Assists in automating the selection of terms to include in mixed models
when ''asreml'' is used to fit the models. Procedures are available for choosing
models that conform to the hierarchy or marginality principle, for fitting and choosing
between two-dimensional spatial models using correlation, natural cubic smoothing
spline and P-spline models. A history of the fitting of a sequence of models is
kept in a data frame. Also used to compute functions and contrasts of, to investigate
differences between and to plot predictions obtained using any model fitting function.
The content falls into the following natural groupings: (i) Data, (ii) Model modification
functions, (iii) Model selection and description functions, (iv) Model diagnostics
and simulation functions, (v) Prediction production and presentation functions,
(vi) Response transformation functions, (vii) Object manipulation functions, and
(viii) Miscellaneous functions (for further details see ''asremlPlus-package'' in
help). The ''asreml'' package provides a computationally efficient algorithm for
fitting a wide range of linear mixed models using Residual Maximum Likelihood. It
is a commercial package and a license for it can be purchased from ''VSNi''
as ''asreml-R'', who will supply a zip file for local installation/updating (see
). It is not needed for functions that are methods
for ''alldiffs'' and ''data.frame'' objects. The package ''asremPlus'' can also
be installed from .'
