A ZAXlist
object is a representation of the “ZAL
” matrix as an S4 class holding a list of descriptors of each ZAL
block for each random effect.
A Kronfacto
object is a representation of a Kronecker product as an S4 class holding its factors. Methods defined for this class may avoid the computation of the Kronecker product as an actual matrix of large dimensions.
This documentation is for development purposes and may be incomplete. The objects and methods are not part of the programming interface and are subject to modification without notice.

LIST
:A list whose each element is a ZAL block represented as either a (M|m)atrix
,
or a list with two elements (and additional class ZA_QCHM
): ZA
, and the Cholesky
factor Q_CHMfactor
of the precision matrix (L=solve(Q_CHMfactor,system="Lt")
).
BLOB
:An environment holding lhs
and rhs
, the factors of the Kronecker product, and other objects initialized as promises. See the source code of the non-exported .def_Kranfacto
constructor for further information.
