Extract reStruct Log-Determinants

logDet.reStruct {nlme}

R Documentation

Calculates, for each of the pdMat components of object, the logarithm of the determinant of a square-root factor.

## S3 method for class 'reStruct'
logDet(object, ...)

`object`	an object inheriting from class `"reStruct"`, representing a random effects structure and consisting of a list of `pdMat` objects.
`...`	some methods for this generic require additional arguments. None are used in this method.

a vector with the log-determinants of square-root factors of the pdMat components of object.

  B = pdDiag(2 * diag(4), form = ~Educ)))
