Description: 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 .
