pdCompSymm-class {Matrix} | R Documentation |
A class of parameterized positive-definite symmetric matrices that have compound symmetry. That is, the diagonal entries are constant and the off-diagonal entries are constant.
Objects can be created by calls of the form
new("pdCompSymm", ...)
or
by calls to the constructor pdCompSymm(...)
param
:"numeric"
- a parameter
vector of length 2ncol
:"integer"
- the number of
columns (and rows) in the matrix.form
:"formula", from class
"pdMat"
- an optional formula relating the object to a model matrix. Names
:"character", from class
"pdMat"
- dimnames for the matrix
Class "pdMat"
, directly.
signature(x = "pdCompSymm")
: get the parameter vector signature(object = "pdCompSymm", value =
"numeric")
: set the parameter vectorsignature(object = "pdCompSymm", value =
"matrix")
: set the parameter vector from a model matrixsignature(from = "pdCompSymm", to = "matrix")
:
get the positive-definite symmetric matrix represented by the object.signature(object = "pdCompSymm")
: get the
matrix represented by the object as a correlation matrix (with
standard deviations)signature(x = "pdCompSymm")
: get the dimensions of
the matrix represented by the object.signature(object = "pdCompSymm")
: check
if the object has been initialized.signature(object = "pdCompSymm", covariate =
"missing")
: get the logarithm of the determinant of the matrixsignature(object = "pdCompSymm")
: get a
square root factor of the matrix represented by the object.signature(object = "pdCompSymm", factor =
"logical")
: get the positive-definite symmetric matrix
represented by the object.signature(object = "pdCompSymm")
