"corDesign"
specifying
fixed, nested, balanced or unbalanced
block designs for multiblock or multilayer correlation structures.
Some components are used for internal computation.
Apply the summary method to see the description of the object.
These objects are generated by function
corDesign
.
The class
"corDesign"
has
print
and
summary
methods.
"corDesign"
are lists
with the following components:
"block"
for a balanced or an unbalanced block design,
"nested"
for a nested design,
"fixed"
for a fixed design matrix, or
"indep"
for
an independent correlation matrix.
type
for the type of a layer,
x.layer
for
the variable associated with the layer,
n.blocks
for the
number of blocks in a layer,
n.cells
for the number of cells in
each block, and n.par for the number of parameters used in the layer.
"all.x"
,
which is a list of two components,
names and map
,
in which
names
refers to the names of variables in
x.layer
, and
map
is an incidence matrix with each row mapping
a layer to the variables in
names
to indicate the usage of
variables in
x.layer
.
type.layer
for function
corDesign
.
layer.id
corresponding to the row order in
type.layer
.
layerblock.matrix
.
design.matrix
and
block.matrix
with
the "integer" part indentifying the
layer
and
the "decimal" part identifying the block within the layer.
parameter
identifying the parameterization and
layer.id
identifying the layers associated with
the parameter id of that row.
cell.id
for row-wise position
of the cell in
design.matrix
,
par.id
for parameter as listed in
parameterInfo
,
cell.layer
identifying the
layer to which the cell belongs,
and
cell.block
identifying the block
to which the cell belongs.
design.matrix
.
design.matrix
.
Variables
par.id
and
cell.id
are as described in
parameterInfo
and
cellInfo
, and variables
x.row.id
and
x.col.id
are the row and column coordinates of
cell.id
.
type.design
is either
"fixed"
or
"indep"
.
record.names
and other variables used in the design.
The object is mainly used to specify the
correlation
argument in the
geeDesign
function.
It is also a component of a
"gee"
object.
