data-rats

rats

<p>An artificial dataset. 24 rats (12 female, 12 male) have been randomized to
use one of three drugs (products for loosing weight). The weightloss for
each rat is noted after one and two weeks.</p>

datasets

The 'gRbase' package provides graphical modelling features
used by e.g. the packages 'gRain', 'gRim' and 'gRc'. 'gRbase' implements
graph algorithms including (i) maximum cardinality search (for marked
and unmarked graphs).
(ii) moralization, (iii) triangulation, (iv) creation of junction tree.
'gRbase' facilitates array operations,
'gRbase' implements functions for testing for conditional independence.
'gRbase' illustrates how hierarchical log-linear models may be
implemented and describes concept of graphical meta
data.
The facilities of the package are documented in the book by Højsgaard,
Edwards and Lauritzen (2012,
<doi:10.1007/978-1-4614-2299-0>) and in the paper by
Dethlefsen and Højsgaard, (2005, <doi:10.18637/jss.v014.i17>).
