Extract reStruct Log-Determinants
DESCRIPTION:
Calculates, for each of the
pdMat
components of
object
,
the logarithm of the determinant of a square-root factor.
USAGE:
logDet(object)
REQUIRED ARGUMENTS:
- object
-
an object inheriting from class
reStruct
,
representing a random effects structure and consisting of a list of
pdMat
objects.
VALUE:
a vector with the log-determinants of square-root factors of the
pdMat
components of
object
.
SEE ALSO:
,
EXAMPLES:
rs1 <- reStruct(list(A = pdSymm(diag(1:3), form = ~Score),
B = pdDiag(2 * diag(4), form = ~Educ)))
logDet(rs1)
