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)
